I don't think they do. In fact many of the atheists i met are very open minded about religion. They actually respect religious people. So no, they don't hate religion. They just don't believe in it.
Open-minded to what? Regardless, the terms do not represent comparable things or concepts.
Atheism simply means a disbelief in deities. It is not a belief system, religion, philosophy, or lifestyle. Other than not believing in God(s), Atheists have nothing else in common
Except that when you Google or DuckDuckGo search on "atheism religion" you get all kinds of sites that show that atheism is essentially a religion. Of course, you get other sites that deny such. But when you do the comparison yourself, you'll see that there isn't much, if any, difference between what it takes to make a religion and the thing that atheism is.
In other words, atheism is a religion that is different from most formal religions in two major ways:
1. They express that there is no god/God;
2. They often express that they are not a religion.
