Ok.
If God is all loving and all merciful then salvation has to be universal - it's not logical to believe that such a God could behave differently.
Yet scripture flatly contradicts this and universalists go with 'feelings' about God rather than 'facts' in the Bible (I know, I've been one).
Hm. Does it though? I was reading around the subject not ever so long ago (I was researching something about the Quakers, I think, and followed a link to a link to a link to a link ... as you do) and the universalists think they have scriptural support for their position - they can and do dial up all the appropriate verses.
Perhaps the simple if rather dully predictable truth is that scripture contradicts itself and contradicts the contradictions all over the shop. Sloppy work for omnipotence, as I always say.
As an aside, no other debate I've ever had has been so venomous as that I once had with a group of Christians on another forum years ago when I stated that I was a universalist. In the end I was told I wasn't welcome there.
That's all-embracing love and charity for you.
