But we're not talking about "private citizens," we're talking about elected officials. They have no right to such personal expressions when they stand in that office.

Where is it written that an elected official gives up his/her right to religious freedom when they are elected?

Who is abrogating their religious freedom? No one.

You don't have the "freedom" to be insulting to others when you are a legislator. You represent all your constituents, not just those with whose religious tenets you agree.
