Ayaan Hirsi Ali now claims to be Christian.

[brewer]

Based on that, apparently she's just a humanist looking for some extra power and control. Or am I missing something?

Power? Control? Not at all from what i see.

Considering her background (as far as i know about it) she is still confused, still looking for answers, purpose, etc. She isnt looking for whats true but for what (she believes!) makes her life better, and that of others.Truth value of what she is promoting seems to be of absolutely lesser importance to her it seems.
I am really curious when she is confronted with and has to defend the anti-humanist, discriminatory and misogynist part of the christian belief. Ill bet a paycheck she is gonna answer by cafeteria christianism. Probably she also will find herself defending the position that she actually still does not believe a god exits (nothing in her article gave a hint to a newly found god belief!), while promoting the christian religion which is founded on such a god belief. Either way, she will have to bend over backwards.

I get that she is looking for her own and her fellow humans betterment, but doing that by ignoring that truth matters.....thats plain stupid. Sorry, but even an idiot like me knows better.

Possibly, but I still think that she's flip flopping for the backing of the christian believers and their position of hating Islam. Don't have the power or control to change from within then switch teams, Islam-Atheist-Christian.
