The whole point of a drag queen is to be a parody of a woman. Why the fuck are we seeing that as something that we should deliberately put in front of children and teach them to ignore their feelings of unease about?? 
I know drag itself is for adults, sexually charged, drugs involved etc
So why are you ok with it being brought to children, even when heavily modified?
Drag story time isn't encouraging that though surely? Like having a clown do tricks in a school, they aren't there saying "you should all start learning to juggle and paint your face now".
Then what is it encouraging, and how does a man dressed in drag help those goals?
In the school setting the drag queens are literally just reading a story, usually with a positive LGB message. They aren't making crude jokes and won't use their same stage name
Hopefully you've seen all the evidence on this by now that no, they're not just reading stories, they are twerking and flashing etc etc.
It's not usually a positive LGT purpose but a positive T purpose.
And I go back to... if they are just reading stories (which stories?) - then for what intent or purpose?
Am I being unreasonable in thinking that DQ story time isn't actually that bad, and in fact does send children a positive message particularly to the gender non confirming/LGB/those with LGB family members?
Why do you leave T out of your acronyms in this post, when drag queens are mainly all about the T?
Lgbt+ education for kids doesn't need to be delivered by a man dressed as a hyersexualised parody of a woman. I don't see anything positive for the kids to gain from it. I've been involved in delivering lgbt+ as a subject to quite young pupils. We talk about some people fancy the same sex and that's okay, we talk about how some people prefer to dress as the opposite gender and that's okay, and then we go on to talk about all these people who are doing cool things and one of the least interesting things about them is that they happen to also be L or G etc.
I just don't get why a drag queen reading a storybook badly is beneficial to children in any way. I think if it were part of a well thought out program of diversity whereby eg every friday people with lots of different skin colours, gender presentations, visible and invisible disabilities, eg speech impediments etc then.... then actually, I would still find somebody who represented highly sexualised and misogynistic views of women, an inappropriate person to invite to read books to children.
