dont make yourself a fool by taking it too serious if s.o. disagrees with your taste. you can always only like sth if your brain associates any positive things with it. same thing works reverse, if you got negative associations you wouldnt like it, even if it were aestheticly appealing, or would you buy skin with swastikas on it?
its also a matter of fact that nowadays only trashy ppl get theirselves tribal tattoos or tribal sticker on the rear window of their cars. you could even make some scientific study about it to find out that these ppl are on average less educated, more appealed to violence, higher chance of teen pregnancy and have less interest in sophisticated arts. saying that, it doesnt mean that this applies to every individual and therefore we also shouldnt treat them with prejudices.
edit: to give you an example from pop-culture: why do you think is the character "Juice" from tv-series "Sons of Anarchy" portrayed with these tribals on his shaved head? it is even literally said at some point that they are a desperate attempt to show off some warrior mentality
