the UK is only the beginning, an end to internet anonymity will happen within your lifetime, likely very, very soon.
can you guarantee you will not be jailed for wrongthink?

I feel like the main problem with so many nihilists is that they refuse to take things seriously because 'nothing matters', but they will become very pressed if you don't take them seriously.

Of course they'll deflect and go "dude don't take it so seriously lol" if they say some shit that pisses people off, but if you refuse to give what they say any credence in general, then they'll get bitchy.
