I'm not picking on you, but I think this is part of the problem with some people and their relationship with Star Trek. Not every Klingon is a warrior, the franchise mostly treats them as such. Just because a couple a Abramsverse Klingons have piercings doesn't mean that every Klingon has piercings. Just like because 99% of Klingons we see are warriors, doesn't mean 99% of Klingons are warriors. Some people just seem very uncomfortable with any variation from what they've come to expect. Both with and without. It explained the tattoos as part of the Romulan grieving process.
