Because every so often I actually enjoy a good argument, my husband, however, does not. Additionally, this forum allows the use of vulgarity and some direct insults, which virtually none do anymore, this is particularly the case with a lot of the "headier" forums.
And, incidentally, if someone makes a valid point that contradicts me, while I may (or may not) acknowledge it here, I will think about about it and take it into consideration in my day to day life. I've actually learned a lot about people hanging out in this forum.
