Everyone draws their own boundaries based on what is important to them. I do not think your example is unreasonable.
But the homelabbing scene, and many parts of tech in general, are generally more inclusive than many other scenes, perhaps partly because we have a very diverse community in the first place. I think it is important context, and not just a needless detraction, for a physical gathering that the organizer does not share these views.
Regardless, I do not think any interpretation of "positive community" can include the dejection of homosexuality.
