Why people make such a big deal out of this, I'll never know. Its like half the forum are living in a 'bubble' of sorts, they're so used to text being the default color and size, that the second they see someone using a new font/size/color they become scared and the only thing they can think of doing is calling that person a moron, out of fear of change, and someone popping their bubble.
I for one have no problem with this, unless the person does it in such a way that its hard to read.
