As an Atheist, do you love someone so much that you care about their soul?
Not speaking for him, but as a fellow non believer, for this statement to make sense, you'll have to demonstrate a soul exists first.
As an Atheist, do you have any idea about the difference between ignorance and defiance?
I believe you are conflating "ignorance and defiance" with someone being simply unconvinced of the god claim(s).
But it's okay for those that don't believe in God's salvation to soil the name of my God and to downplay the righteousness of the Word?
Yes, it is ok to blaspheme religious claims in the public square, at least here in America where 1A still is present. We dont have blasphemy laws here in the states, unlike other theocratic countries have had, and currently have, throughout the world.
You say downplay, others may say, "need more evidence to accept your claims".
