But...There was exactly one person saying "no, don't do it" - Grue, jokingly, answering a rhetorical question. Otherwise, a few people said "I wouldn't do it because I can't think of anything I want permanently etched on my body" which is a...perfectly valid position? The conversation sounds kind of negative, but if you look at it, the general opinion ins, I think, positive.
Grue semi-jokingly said no. PatrThom said "be careful, if in doubt, try a temp first". Gas, me and Bones said "I personally wouldn't do it because I can't think of anything I consider important enough to display on my body, but you do what makes you happy". Rendar, HCGLNS, Squidley, you, Ravenpoe and Hailey are firmly in "yes". The only one being somewhat more negative is drifter, and even he says it's a sick design, but maybe try a temp first.
I understand it's an issue a lot of people seem to take very seriously and/or see as an attack on personal values really quickly, but...well, I assume ti's because they come from a place/area/family where tattoos were big nono's or something? Neither the discussion here, nor the world at large in modern parts of society is very negative towards it, especially in a fairly inoffensive spot like the shoulder/bicep.
If he was suggesting tattooing a big dildo right across his nose and forehead, I'd be offering slightly different advice.
