You're allowed to, of course. I'm allowed to criticize you and vote the opposite direction, which I will do, because I refuse to control people based on my feelings when I do things that are logically the same. I don't like being hypocritical.
Welcome to the world. It's a rare human who uses rationality alone as his guide. Vast majority of people hold various positions and views that are logically indefensible. They get offended when you point it out and their denial kicks in. Stupidity is a curse on humanity. Other big problems in the world such as terrorism, global warming, poverty etc have their roots in the inability of humans to be consistently logical and overvaluing their emotions. If somehow the collective intelligence of human race can be raised substantially, you will see these big problems solved overnight.
