I follow a few people who’s politics I don’t agree with – used to also follow a few #WelshRugbhTwitter types but had to give up on them. It’s healthy to at least see the views of those outside my echo-chamber even if I’m never going to agree with them.
I don’t need to follow Farage or Hopkins. I see most things they tweet as RTs and quotes tweets anyway.
I also follow one person who loves a bit of Tommy Robinson and Anne Marie Walters. Hates immigrants, muslims etc. A bit like some of the RW nut-jobs here – partly for entertainment and also to see what proper looms are thinking.
EDIT:
but risk them thinking they just got another admiring follower,
I think the likes of Farage, Hopkins and other propagatirs of hate realise that not everyone who follows is an admirer. They do however monetise (indirectly) their following on Twitter which is why I wouldn’t add to their number.
