Westboro Baptist Church is "allowed" and legally able to proclaim god caused the death of 20+ kids because he was pissed about Gay Marriage at their funerals. It's "allowed" that a group can meet and demonstrate in the name of, and in honor of, groups who engaged in the wanton killing of minorities due to their minority status. It's "allowed" and legally okay to sit at ones home masturbating to the thoughts of defecating upon a child. Does that mean those things are "Celebrated" simply because they're legal?
I don't particularly find sexuality something that the state needs to "celebrate" in any fashion.
