She's a huge bigot...

I don't think you can categorise into right or left. I know right-wing people who are gay as an example (they're conservative, but they're not MAGA/Trump/nazi's).

It's really better to categorise as "people who want the community to be better and want everyone to be treated well", and "people who want people to receive different treatment".

JK Rowling is the latter. Trump is the latter too. In general though, in US and Australia, extreme right wing people seem to fit more into the latter.. Minorities can also fit into either category too quite easily
