No, atheists don't bother in general. Maybe on the internet, but in rl they don't care enough to bother talking about religion or trying to debunk any.Most people who are atheist do the same. They don't even know the science behind their beliefs and instead just regurgitate one comment from Stephen Hawking or what some other scientist said because they are deemed "smart" and don't actually take the effort to read into quantum physics or anything else as to why Stephen Hawking believes in what he does.
Yet they act like they know the truth and are one sided as well without proper evidence.
And they don't act like they know the truth. They simply tell religious people what they refuse to accept due to a youth of indoctrination. Which is that their beliefs make no sense altogether. So far, the only logical and legitimate interpretation of organised religion is that all those stories are based off of astrology. Whoever says otherwise, should dive into astrotheology before talking.
