Definitely. The internet has a tendency of making minority groups seem majority if they are vocal enough online. Same goes for other types of spergs that acumulate tons of activity on social media.
I don't think any of the irl lgbt people i've met truly fit any of the woke sjw from tumblr or reddit stereotypes, but i've met straight people who do. Gay people are already like 3% of the population, i mean, its still a lot of people but its a proportionally small number, woke gay people who buy into all the kool aid and agenda are an even smaller number and i am pretty sure by my own experience that most lgbt wont even go out of their way to go to pride marches and stuff like that. Compared to online where 2/3rds seem to have some pronoun in their bio and some political manifesto based on their sexuality.
These poly identitarians are actually super rare to see, either in straight or gay groups, they frolic online and are enough to build a community but very few people actually live like that or see it as a normal type of relationship. Even with all the people joining the bandwagon for clout and woke points online the actual irl number is marginal, but then agian, i don't live in a cultural epicenter so maybe in a very liberal american city is diferent. Even then it would be isolated in that type of cultural mileau, like San Francisco's most cosmopolitan districts or something like that.
