So I am Here with My first Question

[mordant]

Your question implies atheism is a faith, as you're asking if atheism can accept "other" faiths.

That is like asking a person who is unmarried if he accepts other forms of marriage. It's a non-sequitur.

Atheists understand that other people adhere to religious beliefs. They vary in their respect for that decision, but in my experience and observation, all of us would be indifferent to what others believe, but for the fact that many religious people try to impose their religion on us. And understandably, we get a bit irritable around that.
