"Is it desperately important they go to pride so I should start researching to know where is genuinely family friendly?"
Not for you, clearly, so I'm guessing you don't have a lesbian daughter.
Is it important enough for me to do that work? Yes, yes it is.
The las - family friendly - pride event we went to we sat in the sun and shared a table with a lesbian couple in their 60s. They chatted to DD about her experiences of their event, they talked to me (when DD was off looking at the stalls) about what it was like for me raising a daughter who is a lesbian, and they shared their own experiences of coming out in a different time.
I'm quite sure your 'good parent' dig was meant to imply that I'm a shit one.
That's where you're wrong.
And you really do sound as thought you don't have the first idea, sorry.
