Why do people think gay people are always a part of the left or the regressive left?

But what makes you think that "people" think that gays are lefties?

They don't. Most people assume gays are liberal tho. For obvious reasons.

Experience.

A number of times have people in real life and online thought this.

It seems to be a really bad case of confirmation bias.

I'm a straight female. I saw photos on Twitter a few months ago a Pride event. It could have been London i'm not sure. Anyway, in the background on loads of the photos were stands to join the Labour Party. The guy posting these on Twitter was a member of Gay Labour [Sorry that might not be entirely accurate, but it was something like that]. I messaged him. I said I had never voted for the Labour Party in my life and asked him if other political parties were also at the Pride event. He said Socialist Worker's Party and the Greens and a few smaller far Left parties. I asked him if the Conservative Party was there. He said they were not. I asked him why not. He said because they probably wouldn't be made to feel very welcome. I then said even though I was straight ,not seeing ALL political parties there would be really off putting and I thought that Pride marches were supposed to be really inclusive. I said how can it be inclusive if they are ignoring gay /BI /Trans Conservative Party members? His answer? People who support the Conservative Party are perfectly entitled to arrange and organise their own Pride march if they want to. So I guess that meant Tories were not welcome then. So much for inclusivity.

Not in my experience.

Possibly younger, more sheltered people might think like that - who personally only know younger gay people or gay personalities that appeal to younger people - but this would follow with young people being more lefty in general.

I'm LGBT, and no-one really cared. But when I said I was conservative, I lost friends (one of whom I thought I was fairly close to) and was often asked to justify my positions.

Well the majority of conservative MPs who voted voted against gay marriage so you can understand the animosity, if not condone it.

On a similar note, when I went to Pride, loads of people were against Brexit and were wearing remain stickers and the like. And I agree with the OP, in my experience LGBT people (especially lesbian and bisexual women) are leftists (and regressives).

Most people conflate "left" and "liberal", so it doesn't really help your case.

(I will say in my experience in case you want to dispute my point. )

Just because some of the Conservative MPs voted against gay marriage doesn't mean that they were against gays or homosexuality. I don't see why they shouldn't be invited to the event. There are gay dos evasive MPs as well.

They are known to be left too. Regressive? I'm not sure about that.

Perhaps it's just me then.

Edit #1: I'll rephrase, I have found that people not on the left seem to think that gay people are on the left or the regressive left. These people don't seem to think that gay people can be on the right side of the political spectrum too.

That's a shame.

Was there even a debate on the matter? (As to why he disagreed with the Conservative Party or conservatism?)
