"This (atheist billboards) is on purpose & would not be surprised if the funding for the militant Athiest movement came from Saudi Arabia."
Saudi Arabia, of course, being so well known for supporting atheists.
"Direct conversion from Christianity to Islam is very rare."
Uncommon, perhaps, but I wouldn't think it's "very rare" since Christians make up 1/3 of the population and Islam is the fastest growing religion at the moment. They've got to be getting their converts from somewhere, and it's likely Christians that are the majority.
"But its much easier to conver to Islam if you believe in nothing first."
So, I believe in "nothing" (which atheists don't, but I'll let it slide) so, by some strange line of reasoning, it's now easier for me to start believing Islam's bullshit over, say, yours that is damn near ubiquitous to my culture?
"Atheism is just a way station to Islam."
Atheism tends to be the last stop rather than an intermediate destination.
Once you realize all religions are pretty much the same (i.e., unfounded bullshit) there's really nowhere else left to go.
