1. You could say that about any course... Statistics comes to mind.
2. The original justification was "everyone should learn basic reasoning". You just turned it into "kick out people who can't learn it, cause screw those guys".
Many people do take that opinion though. I've seen it reasoned, and felt it a little bit myself, that you should take any and every opportunity to say "kick people out who can't learn X" because that's what assures the value of the degree in the first place.
However, that gets into "what does a degree really mean" and plenty of other arguments, not something I'm interested in.
1. I don't believe that everyone needs to go to college.
2. I don't believe college is a day care where students should be coddled. If they can't pass a basic philosophy course, they have no business being in college. That's not to say they are worthless, just that college isn't right for them.
