As a European, I’m biased and say go for it! They being said, Europe has a lot of different climates and cultures to offer so kinda depends what your looking for.
In a perfect world (where you have the money and time to do so), I would suggest you backpack around for 3+ months and see which vibes you like the most. At the very least, I would suggest visiting somewhere in Europe first (even just one place) if you haven’t done so
No tolerance however ends up at the same point.
It’s not like we know this person has Nazi tattoos or even what their views are. Maybe they literally just asked a question. If they do have Nazi tattoos, they can fuck off. If they think anyone who doesn’t identify as strait is a bad person, they can fuck off. If they believe the q-anon conspiracys without question, they can fuck off.
But untill we talk to someone (assuming they are not visibly showing their extreme views like in your bar tender example) it literally doesn’t make sense to judge people based on the information OP has provided. If more information comes out, I am open to changing my opinion, but for now I think you are being intolerant of people joining this platform simply because they ask for something that is not as left wing.
