Nah that wouldn't be the conclusion

The conclusion would be "saying free Palestine, etc. or attending protests is now considered aiding and abetting a known terror group. This applies retroactively as Hamas has been on the terror watch list for some time."

It's incredibly obvious that far right wingers in the US (like 80-90% of congress btw, not representative of the US population but they are the ones with legal power) are pushing the narrative, against all reason and all evidence, that Israel is smol bean innocent, Palestinians are all terrorists, and although laws exist to prosecute people in the US who materially aid terror groups, they very very very much so wish to expand that to any and all "support" for terror groups. Since the entire Palestinian movement has been basically washed with the term terrorist... very clear where the Nazis want to go with that here.

Germany's already on the final steps of this idea. Wouldn't surprise me to see the rest of the EU just follow along especially if an attack happens (legitimate or not doesn't matter. The fact that an attack could lead to these restrictions just tells me it will inevitably happen unless something is done about the root problem which is Zionist propaganda but even further to getting rid of the arbitrary term "terrorist" that has been used to justify anything for ~25 years now... longer, but especially since 9/11.
