Indeed.
If I was to name all the games that I find incredibly fun, where general opinion is they sucked, I'd probably need more than a reply box. Conversely, if I were to name all the games I found to be an incredible bore and that have a large fan base, I'd probably need a day off.
Unfortunately, instead of often expressing preferences positively by concentrating oneself on that which we like, often they are expressed negatively by affronting non preferences. As if somehow I needed to justify the fact I like something by making irrational claims about something I don't like. And irrational they are. As irrational as our preferences are. If one wanted to go deep into understanding why they like something better than something else, they would find themselves in trouble. We simply cannot explain it. But a judgmental and viral fan mentality that unfortunately infected the tech industry, has many believe liking something is the same as being right.
It's... and here I'm probably becoming offensive, but I don't mean to... a typical teenager behavioral pattern that tends to disappear through adulthood (some certainly won't). It's because of this that it is so visible in the gaming industry. But it finds also an echo on the tech industry as a whole. The difference being that as one gets older, wiser, less caring, their preferences won't change. But the way they express them will.
This isn't me on a high horse. Instead, noting that being passionate about something obviously makes it impossible any sound judgment. Also negating how little we know of ourselves and what makes us tick. But both are very common mental patterns; in the young particularly, but some adults too. There's no actual shame in it. But I'd rather have more people realizing this before they go on to propose I suck because I like X. Or that X sucks because they don't like it.
