The negative comments towards tattoos on this thread shows exactly what is wrong with society. Its ok not to like them, but to label people as mentally ill or bad people because of a tattoo is truly disgusting behaviour.
Depends on how you wear your tattoo I guess and what you are trying to say with it. You make choices in life as to how you present yourself to others. Some of those choices are temporary, hair colour, piercings, clothing, make up etc. Tattoos are permanent and again you are projecting a certain 'image' depending on what ink you have applied to yourself. I have seen some amazing tattoos in my time, however, many to me, just look bad and generally look worse over time as you age.
The blokes who hang out in a Chelsea supporters pub near me are covered in club insignia tattoos, the impression I get is that they are worn as both a badge of honour and as a 'fuck you' threat to others. Knowing the history of that clubs supporter base and the shit they got up to in the 70s and 80s I would judge negatively anyone of a certain age sporting ‘Chelsea Headhunter’ tattoos as they were closely aligned with Combat 18, National Front and other violent racist groups.
The Maori lads I used to play rugby with had amazing tattoos on their thighs, they were not just random 'on trend' artwork, they told a story, it reflected the individual's whakapapa (ancestry) and personal history (tribal and family).
I am more likely to label the former as 'bad' people and the latter as decent as their nature of their tattoos speaks volumes about their mindset.
