I'm not into heavy tatts but if I was I wouldn't hesitate to bring her home to mom.
I'm ashamed to admit it but my mom probably wouldn't be happy if I brought home a black girl either. Or a Muslim girl. I love my mom but she is very judgmental and I would not let that affect who I choose as a partner.
Basically, if I liked the girl enough to introduce her to my family, I wouldn't care what their preconceived judgments would be.
But it's all moot as I'm happily married to a half Dominican girl with a tatt.
