People who haven't studied guns tend to assume that the evolution of small arms towards an assault rifle was in someway inevitable.

I'm here to say that this doesn't follow.

In this thread, I'll pickup on the US crossovers I referenced but didn't cash out in my last thread

Wow! Rare moment of truth at the UN as Miss Iraq Sarah Idan calls out Hamas terrorism, antisemitism taught in Muslim countries, and biased media.

THREAD: "Two years ago, I represented Iraq at Miss Universe. I posted a photo with Miss Israel on social media..."

"I was told to remove it and forced to denounce Israeli policies. I received death threats. Since then I can no longer return to my homeland.

Why did the Iraqi government fail to condemn the threats, or allow my freedom of speech?"

"The issue between Arabs and Israelis goes beyond policy disagreements. It’s deeply rooted in the belief systems taught in Muslim countries, which are anti-Semitic."

"Sadly, hatred & intolerance are reinforced by biased media. When I watched the news last month, why did they never report that the Hamas terrorist organization fired nearly 700 rockets at Israeli civilians in one weekend or that Hamas used Palestinians in Gaza as human shields?"

"Why do they never condemn Hamas for initiating the attacks? Instead, they only show those killed by the response, in self-defense, and blame Israel."

1/14 How do e-cigarettes (ECs) affect cigarette smoking among youth? My new paper with @FloeFoxon simulates each scenario and finds out which one best matches actual trends... https://t.co/dBB7kcnTls @jgitchell @mikepesko @SwitchFinder @jkelovuori @TobPolicy @Clive_Bates

2/14 First, let's talk about why this question is so difficult to answer: COUNTERFACTUALS. We can't know the alternate-reality answers, like which smokers would have never started in a world without ECs, and which nonsmokers would now be smoking without ECs as an option.

3/14 So, the best we can do is use fancy/sophisticated methodologies to estimate what would have happened to youth smoking rates in the absence of ECs. In our case, simulation modeling

4/14 First, we look at the declining smoking trends *that were already happening* before ECs came (~2010), and project them into the present. This is our BASE-CASE SCENARIO about what smoking trends would be if ECs were never invented. Actual trends were LOWER than this base-case

5/14 Side note about terminology: We use the term “catalyst” instead of “gateway,” because “catalyst” is more precise about the claim we are modeling (that ECs are used first, and then causally lead to smoking). Whereas "gateway" can include other mechanisms like renormalization.

*Heads-up that this thread will feature some extreme examples of homophobia and transphobia.*

Hey folks, have you ever wondered why trans people face constant accusations of fetishism, sexual predation and child abuse/grooming? Well, today let's talk about stochastic terrorism.

So, first we have to talk about what stochastic terrorism actually is. Remember when there was a conspiracy that there was a pedophile ring operating out of a pizza parlour basement, and a crazed gunman showed up? It's that sort of incitement that stochastic terrorism describes.

It's the demonisation or incitement against a group of people or individuals with the intent that other, unaffiliated parties will act upon it; it's the releasing doctored footage and a shooter show up at Planned Parenthood as a direct result of what he's been led to believe.

So with that in mind, let's talk about Russia's extreme anti-LGBT laws that banned the "promotion" of LGBT lifestyles to children. A move that specifically marked LGBT people as a threat to children, and resulted in neo-nazis meting out vigilante "justice" against gay men.

Groups such as this would lure unsuspecting gay men via dating sites, and brutalise and humiliate them on camera. They did so under the guise of combating child abusers, one group calling themselves "Occupy

@danielashby @AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd I'll bite. Let's try to keep it factual. There's a reasonable basis to some aspects of this question, that it might be possible to agree on. Then there are other, more variable, elements which depend on external factors such as transport and energy policy. /1

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd First up, we know reasonably well how much energy it takes to propel a high-speed train along the HS2 route. We can translate that into effective CO2 generated by making some assumptions about how green the electricity grid is. /2

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd Secondly, we have a reasonable grasp of how much CO2 is going to be generated by building HS2 - there are standard methods of working this out, based on the amount of steel, concrete, earthmoving, machine-fuelling etc required. /3

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd Thirdly, we can estimate how much CO2 is generated by cutting down trees, and how much is captured by planting new trees. We can also estimate how much CO2 is needed to keep the railway running and generated by maintaining the track /4

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd We know how much CO2 is saved by moving goods by freight train on the lines freed up by moving the express trains on to HS2, rather than by truck. /5
