If he wasn't trying to say that Christians are stupid, comparing a Christian college to dim teachers is misleading. Why is this being brought back anyway? It has nothing to do with the discussion.
No it isn't private Christian Colleges have a well deserved reputation for teaching the sciences poorly, if at all.
The person who made the original statement, whose religion was never disclosed, made a statement that was erroneous scientifically. I doubt the statement was ever made in seriousness at all as it is a well known philosophical saw used to promote discussion.
But, taking the statement at face value I would have to conclude
1) The teacher was stupid
2) The teacher taught at a Christian College and was making an anti scientific point
3) that the teacher was both
Let's examine this for clarity, could any reasonable person read that and come to the conclusion that I think all Christians are thick?
I think they would either have to be rather stupid themselves, or be so defensive about their religion that they saw slights everywhere.
Considering we don't know the faith of the teacher involved all we can logically conclude is that I think this teacher is either stupid or has an anti-science agenda or both.
In fact conclusion 2 leaves the door open for this teacher to be clever but have nefarious anti-science motives for making the point.
The only point where religion was mentioned at all was in the prefix "Christian" to the word college, because those are the schools that I associate with an anti-science agenda and Christianity is the majority faith where this alleged event occurred.
I can't believe I am having to explain such an innocuous statement to this guy.
