AITH for telling a BOE member I hope he loses his job?

I live in a small town in the Northeast. My kids are in the public school system. The Board of Ed recently voted to make uniforms mandatory for all students starting this school year. A lot of people are upset because it's expensive and, honestly, we just hate uniforms. They are ugly and we are mad that nobody really listened when parents said we didn't want them. Uniform pickup was this week and the head of the BOE was there helping to hand them out. I was annoyed and told him "I hope this was worth it because I will never vote for you again and I hope you lose your job over this". I was told I was mean and should have just accepted it and moved on. In my eyes, I did accept it. I bought the stupid uniforms and told my kids that they have to wear them and follow the rules. But I think the board needs to remember that they are elected officials and pissing off the people that vote for them is going to hurt them.
