There is a lot of generalization, prejudice, and ignorance around tattoos on girls in the manosphere.
No, they are not for cattle or to mark masses. Tattoos have been around since almost the beginning of humanity. They are a sign/symbol of a rite of passage. Originally, and ideally, in modern times they mark something of importance to that person and that person alone.
I might be biased as I have several. But as long as she is not covered up and they are all off-the-book, cookie-cutter, with no depth/meaning, then I don't mind one or two. As for the area, ideally not overly visible, yes.
Again, this comes down to ignorance and prejudice. Take some effort to get to know the girl. Now if you, yourself don't like tattoos, well then that is just your standard and something you are not attracted to. Fine, move on. But don't stereotype women with tattoos. Again, I have a bunch so I might be biased but I also can't be that ignorant and hypocritical to not understand if someone has a valid reason and meaning for a tattoo. Ideally, a rite of passage and not just a drunk tattoo.
