to allow the existence, occurrence, or practice of something,in particular the existence of opinions or behavior that one does not necessarily agree with.
A way that I can be more tolerant is by not saying anything that comes to mind when I hear a certain race or religion. An experience I had with less tolerant people was when my aunt came out that she was gay and her mom didn't accept it so she moved out and she wasn't invited to a lot of family events. This showed me to accept people and not let there sex and things like that from me excluding that or discriminating, and especially in family.
