So, brass tacks and all, this is where we get down to 'what is representative', and what isn't.
So how many pride parades are there in, say, USA and the UK alone?
I mean, thousands?
How long do those parades last? Here, it's a weekend, basically.
A dickhead with a dildo doing stupid shit and embarrassing themselves might happen, but in how many parades does that kinda nonsense happen, and for how long?
If it was 'a lot of gay pride parades' (your words), I'd have seen it. I've been to 3 and it's harmless fun, so chances are I'd have seen it at least 1 time.
