Liberal values are not at odds with Christians values. It is entirely possible to be a Christian but to be grown up enough to know that other people don't believe the same and to not think it's right to impose your belief on them.
But Christianity is a proselytising religion. Again, out crassly, as a Christian, your aim is to save people, to get them to see the light and believe what you believe. And part of that is that there are objective rights and wrongs, as set down by an all powerful God. So I think they are at odds over quite a number of things.
