There are a subset of Scottish Nationalists that genuinely think that anyone disagreeing with them is a troll with several usernames.
I used to think it was just a defence mechanism, but over time I've reached the conclusion that they are being genuine.
Sad eh? They are best ignored. If you behave in the same way back, then it'll be you that gets the ban. Sad but true.
The mindset of the SNP is to ban ban ban, and that filters down to their supporters. Humza's hate speech laws are an absolutely disgrace in a supposedly free society. It's fascist, as you rightly say.
