Don't be so open minded that your brains fall out.
Just about every relativist I have met argues for his relativism or at least tries to give reasons why my nonrelativism is inferior, misguided, mistaken or intolerant. As if that weren't odd enough, the relativist often gets angry when I simply point out that, according to his own relativistic claims, it is impossible for his views to be “righter” than mine. After all, relativism is “just his opinion.”

Relativism is the belief that there is no objective truth due to the fact that beliefs are affected by the ideographic details of the person holding them.
We're constantly chided that “it's all relative.” The next time someone says this to you, ask them: “It's all relative to what?” It's like saying “everything is up” – it lacks any actual meaning.
More recent versions of this are “everyone is where they are” and – the worst of the bunch – “thank you for telling us your truth.”
I was once a Unitarian Universalist; a small religious group that traces its roots back at least to the 1700s that likes to quote Thomas Jefferson where he stated that within a generation, every thinking person would be a Unitarian. You've possibly seen their bumper sticker, showing symbols from multiple religions. This was a nice group of people, but after a fairly short time I started to think of them as “the church that won't say 'no' to anything.”
It's true that you can find truth in many religions; In fact, I often draw from multiple religious sources in this blog. But it's also true that even a blind monkey periodically finds a banana and that a stopped clock is right twice a day.
There is no “your truth” – there is only truth. No human has a perfect handle on the truth, but that doesn't mean that we should mix it up with mere opinion.
