Problem there is that what counts as discrimination is a constantly-shifting morass of subjective viewpoints.
'No religion' just means 'no evil Judeo-Christianity, anything else is fine because they're enlightened and peaceful'.
'No politics' means 'only the party-approved opinions are allowed, anything left of Mao is automatically fascist, also feel free to spam rainbows and put pronouns in bio'.
'No economics' means 'allow me to continue believing in whatever socialist drivel I was taught in school and on tumblr, but communism can definitely work and has never been tried'.
