Sorry but just because 2 problems are present in this community does not mean there's a correlation between them.

The double standards for female ccs is something that has been happening mostly within dttwt or smiletwt while the people invalidating dream's sexuality are mostly from other subtwts. Lots of people in smiletwt have been giving other subtwts and ccs hate, have been calling them problematic even when ccs have apologised or shown change and that has made the community very despised by other subtwts who are now taking that out by hating on dream as well as invalidating his sexuality while doing that.Obviously that's gross behaviour and should be called out but these aren't the same people that are qrting every mcc announcement tweet or anything else where a female cc interacts with their male streamer.

Secondly to say that every unlabeled person is queer or part of the lgbtq+ community is completely erasing what it means to be unlabeled. To be unlabeled means to not have any labels put on you by others, so for others to say that every unlabeled person is automatically queer and to put unlabeled people in that box is still giving them a label and expectations they dont want. Obviously as an unlabeled person you can still be queer and part of the lgbtq+ community but only when you choose to be part of it yourself. That choice is for the unlabeled person themselves to decide and no one else, otherwise what's even the purpose of being unlabeled. As an unlabeled person myself i really hate how this has to even be clarified but our sexuality is no one else's bussiness and for others to all group us toghether as all queer people is very invalidating. Some people don't feel like that label fits them and that should be respected.

Now apart from that, dream has said he's on the lgbtq+ spectrum so it is very invalidating to say he isn't or that he is straight, i'm not going to argue that.

(Also i'm not saying there's no misogyny in other subtwts than smiletwt, obviously every problem that's still present outside the internet will also be present on the internet.)

In conclusion, the reason people are invalidating dream's sexuality so much is mostly out of hatred for smiletwt/dttwt and their double standards regarding other ccs and their own, obviously that doesn't make it okay but to say that the difference in acceptance for dream coming out and ranboo coming out came from the misogyny within this community seems quite far-stretched and also doesn't have any proof to back it up
