What you’re calling liberal bias and anti-Christian in this case is likely just the effect of education, Bernaridho. There are lots of students who enter college having grown up in very sheltered environments where a conservative brand of Christianity was presumed true. Some of them experience a loss of faith or a liberalizing of their beliefs (not to be confused with political liberalism), which parents and others in those communities mistake for a concentrated attack on their religious beliefs. An alternative way of looking at this might say that these churches and communities have failed to adequately prepare their children for encountering the broader world and the diversity of belief systems in it that don’t match up with their own. I have heard plenty of Christian ministers and apologists - even conservatives ones - claim that if your faith requires you to shield yourself and inoculate yourself from merely encountering other ways of thinking and living, then it’s a flimsy faith that arguably isn’t worth holding on to in the first place.
On the other hand, though, I know from personal experience that many students also retain their Christian beliefs through the college years. I was friends with a few of them. I also had one or two professors who were outspoken Christians. The idea that Western universities are anti-Christian is a pretty marginal one even among many evangelicals.
But this raises another problem. Your claim presupposes a uniformity to Christianity that just doesn’t exist. You probably know as well as I do that there are many different denominations, interpretations of scripture, doctrine, and so on. Not all of these differences are that significant, but some are. Then by your own rationale, each of these variant views stands against others and is therefore ‘anti-Christian’ in at least one respect, if not several. I think it’s frankly absurd to call something anti-Christian just because it doesn’t sit well with your narrow definition of Christianity.
However, there may yet be something to this because there are those Christians out there who would happily turn our universities into seminaries if they could. They’d throw out the aims of secular education and teach religious dogma and propaganda instead. Framing this as a battle of ideologies is always easily done, but it still runs into the same issues I have outlined above. Whose Christianity should be taught? Why not present a diversity of views, which is essentially what secular education tries to do at its best? Personally, I feel that religious groups who place the tenets and doctrines of their faith first will always tend to indoctrinate rather than educate. At least with secular institutions it can be agreed that the central focus needs to be education. Not so with many conservative forms of Christianity. I think giving them more control of our universities in the name of some misplaced sense of persecution would be nothing short of disastrous.
