Not all atheists hate religion just like not all people of a certain faith hate other religions or try to force their beliefs on others.

Pretty much every group has very in your face/polarized thinking type of people. whether it be religion, politics, sports, foodies, boomers, millennials, left, right, pepsi or coke.
People that are very vocal about something usually dislike the other side for whatever reason and want to be validated.

Most people are not like that, Most people go by the motto live and let live.
