Now, if it still isn't clear to you. You asked for my OPINION and I gave you my OPINION.Don't know of any rule book (Translation: no such rule), and you're free to be as huge an asshole as you want to be (No rule against it.). But you asked if it was wrong, and not what rules or laws were. If you're being intolerant of something that is none of your business, that isn't harmful to others, and breaks no laws, well, you can't call that equal to something that does one or more of those things.
Now, if you say it is fine to be intolerant of anyone, would it be acceptable for me to say who says so? I know it is you who is saying so, as I know there is no rule book. Now, stop the silliness and try making a case yourself.
