This is such a huge problem in atheism communities, which is why I don't spend any time in them despite being secular and non religious myself (yeah, I honestly don't even like using the term "atheist" anymore). Religious or not, you shouldn't be telling people what to believe or how to believe. That goes for hardline Christian nationalists just as much as it goes for hardline Atheists attacking anyone of faith. If it's not hurting anyone, let people believe what they believe.
I agree with this sentiment, but Christianity is partly defined by "spreading the word of god". So "telling people what to believe" is par for the course (think missionaries).
Curious though, why do you not refer to yourself as atheist? Non-religious is actually not very specific. Non-religious can mean Agnostic Theist, Agnostic Atheist, or Atheist.
