I agree that there are a lot of churches in Chicago (I lived there for the first 18 years of my life) and that Obama could have chosen from many of them. But I feel like you view yourself as unveiling a sinister plot that his been in the works by Obama because of something he studied in college and because he chose Trinity.
Further-
Socialism, ideas by Marx, etc. don't make my sirens go off like they do yours. None of these is inherently evil. But rather- governments have done sinister things in their borrowing from/application of such concepts...
There are positive elements of socialism all over America- the way we run our fire departments for instance.
And as far as why he chose Trinity- my tune hasn't changed. My understanding was and still is that Obama chose Trinity because it is considered the largest black church in Chicago.
I am Polish. If I was just getting started in local (Chicago) politics I would likely attend the largest Polish church I could find in Chicago. This makes sense to me.
I don't think I am the only one who disagrees with you. I think I am just the only one goofy enough to bite and keep coming back for more...
