That's a circular argument. "Getting tattoos makes you a bad candidate because it shows that you're willing to get tattoos". You shouldn't want to work for people that think that way. Great way to weed out bad companies if you ask me.

This is just being shouted to the masses, not to you personally: If a qualified candidates only disqualification are his tattoos, he's still a qualified candidate.

Also, I've had visible tattoos (hands, neck, arms) my entire adult life. I've never had an issue with them involving employment. Excluding the time an employer wanted to put pictures of them on their website and I decline. Two weeks later I was laid off. Either they were going to fire me and wanted to take pictures of me on my way out, or they weren't going to fire me and this made me seem like I wasn't a "team player".
