What happened to Heather Heyer was also not speech. What happened to Clementa Pinckney and 8 other African-Americans at the Charleston church shooting was not speech. What happened at the Tree of Life Pittsburgh synagogue shooting was not speech.

Shouldn't the same argument apply to the videos that radicalized those murderers?

No. Why should it?

My parent comment had said that conspiracy to recruit people to commit crimes is not an unreasonable basis for making it illegal to distribute recruitment videos for ISIS, because they are a criminal organization due to their violence, not their speech. That implies that that should also not be an unreasonable basis for making it illegal to distribute recruitment videos for violent white nationalist organizations.

Does that answer your question?

Yes, thank you for explaining. I misunderstood the context of your question.

If you can prove that any particular video did so, sure, I don't see a problem with that.

are you blind? white supremacists kill more people in the west than ISIS

You can improve this comment but removing the question and providing a source for your claim.

Rubbish. You're claiming that "white supremacists" kill more people than the Bataclan murders, the bombing of the Ariane Grande concert and a host of other atrocities (Sweden, etc.) carried out by self-proclaimed ISIS supporters.

That's not only wrong it's highly offensive.

You are offended by an unsupported claim, and proceed to make an opposite unsupported claim. Now I'm offended not by your assertion, but by your lack of substance.

I googled for "extremism murder statistics": This is only the US [1], and I have not looked at methodology, but it supports GPs claim, not yours. Please discuss, but do so using substance, not master suppression techniques.

Well I think the problem lies in that all his examples were from outside the US, and not only during 2018 which is when and where you gave an example. Here's another source that is only in the US that seems to agree with Wildgoose [1](pdf) from 2010-2016. This source certainly doesn't count as many deaths (note your link said their were 313 deaths from right-wing extremists from 2009-2018) it only goes from 2010-2016 saying there were 140 deaths (note your link also says 50 deaths happened by right wing extremists in 2018). I'm not sure what the discrepancy is there in not accounting for all the deaths from your link. This link states that from 2010-2016 68 deaths were from Jihadist-inspired terrorists while 18 deaths were from white nationalists and extremists. Yet again it would be nice to see data from the whole of the West.

Just to give you another source from the same people which seems to agree with Wildgoose's parent atleast with its reasoning (albeit by making a few qualifiers on the dataset that bend it to be in favor of that reasoning) [2] from 2001-2016 in the US.
