Husband won't let daughter attend Pride parade

So I told my husband today that my college might have a float this year and that they asked people to sign up for it and my daughter and I did. He said she is too young to go (she will be 13 in August ) because some men dress in assless chaps and are half naked. As of yet he doesn't know that she is gay. My feelings are that she is old enough and has seen worse on TV probably. My husband said he would go and support me but she couldn't go. My daughter is planning to talk to him tomorrow (she is too upset tonight ) and say that she overheard our conversation and that she wants to go and when he gets into his argument she is thinking of telling him she is gay. I told her that there is still a chance he will not change his mind.

Anyone have any thing I say to him to make him see our side. I asked him to be open minded and think about it but he said he honestly didn't think he would change his mind. I don't want to make it a big fight or make him be defensive. He mentioned that he wouldn't protest if she was 16 or older. She heard that and is so upset. I really wanted to go as well but I would feel bad to go alone. I don't know anyone to go with. I was hoping he would want her with me so I couldn't have too much fun lol. Any help with intelligent counter argument would be appreciated.

 

Oh and my daughter wasnot really ready to tell him just yet. We have been talking about it for a couple days now. I was asking her if she planned to tell him soon and was leaning towards it being a good idea. She didn't want him to be weird about her sleep overs and think that her friends are her girlfriend or something. I'm the more laid back parent and he is pretty strict. Anyway I told her that it is not for me to say when she tells people. It is hard knowing that I know and he doesn't. Oh I told her if she does go through with her plans that she needs to say it to both of us or he will be upset that I knew.

 

Abigail15 - no I don't believe he expects anything about her being gay. I don't think he would say no because of that. I think he wants to protect her from adult themes. I think if it was a straight parade with the chance of half naked people he would object. He is very protective and strict when it comes to the kids. I feel it is almost smothering lol. My goal is to get her to as many lgbt events as possible so that she feels part of a community and doesn't feel secluded. I want her to be happy. Hope that makes sense but it is very important to me that she has a lot of positivity about being gay. Plus I really want to go to more things because I feel so comfortable at them.

 

My son is 22 goes to school works but still lives with us and my husband is still a little smothering with him. In contrast I remember my dad and grandma took me to Black's beach which is a nude beach when I was maybe in 1st grade or so. I'm more like don't get hurt or arrested and it is fine lol not really but that is what my husband thinks. Oh he said he would want to come support me but doesn't want to see the nudity himself or think it is appropriate for our daughter.
