I would say that DannyTN has so much respect for all people that he is deeply concerned about atheists and where they spend eternity. Therefore he evangelizes everyone. DannyTN has a great deal of respect for others, I'd say.
I may understand if he was trying to convert his own children, although I doubt he'd have to do that; surely the initial indoctrination will be sufficient.
However, we are talking about adults with as much right to their beliefs as he has to his. Perhaps the atheists should be worried that he's living in a delusional state, wasting his current and only life away on false hopes of something greater afterwards. That sounds like the exact respect out of deep concern you describe, although I believe it would be equally disrespectful.
