Being UC, this may surprise some of you, but I am not against facial hair. God made it on men.
Now, I am against it on women. They need to shave it all off!!!
Seriously, I have looked into this and there is a lot of scripture that can weigh either way. I feel that it is a matter of preference.
Many do believe that if a man is wearing facial hair then he is hiding something. For some, it is just plain hiding the ugly underneath.
I used to have a fairly full beard and mustache. I shaved it because I felt like it was the right thing to do. I will continue to do so. But, I do not condemn others who wear it.
