Their rhetoric is very much Nazi aligned. Have a look at their longer comment in here. Claiming to be taken out of context and that meaning “not evening crossing” their mind, before immediately stating they did mean the “living space” remark in a genocidal manner. Just on behalf of the Palestinians.

To claim those being genocided are actually the ones who are genocidal, which implies post-hoc justification of Israel actions against them (alongside the protestor rally tangent), is Nazi behaviour.

To respond to someone providing the figures for the appalling number of civilian casualties over a short time frame with “at this rate it would take 300 hundred years to exterminate 2 million of them ” is Nazi adjacent behaviour.

Maybe they’re just a particularly uninformed Zionist. However, neo nazis don’t typically wander around saying “that hitler guy is pretty swell amirite guys”. They excel in skirting around moderation online and irl. Hence the nazi bar anecdote; they use free speech as a shield and coded language/dog whistles. If they aren’t a Nazi their behaviour and rhetoric needs some serious introspection.

Edit: I spent too much time going through their post history. Given they post all throughout the day, say they “work at home 7 days a week” and their references to their age; I would guess they’re a retiree that mainlines sky news or adjacent media. Given the boomer - social media to alt-right, brain rot pipeline - checks out with a lot of their remarks on Muslim’s/the Arabic sphere.
