The issue isn't necessarily that you stated your opinion. The issue is the original post here, and the same people in 2-3 other threads loudly declaring that they hate positionals and asking for them to be removed. There are people on the other side of the coin feeling the need to vehemently defend positionals so that a small joy of the melee DPS isn't stripped out because some people "don't like it." It's especially bad whenever the same people asking for positionals to be removed are saying that they make up less than 1% of total damage during a fight.
I'll admit, I'm pretty new to the game, coming up on 1 year in a couple of months, but it seems like the "high end" players are tired of seeing the skill ceiling continuously pulled down by people who seem like they "just don't feel like trying." The fact of the matter is that IF the math checks out and positionals make up less than 1% of total damage (those numbers are suspect, whenever I went through it seemed like it was more like 4%-8% with SAM on the low end and MNK on the high end, but I'll concede to <1% since I just looked at potencies and "guessed"), then people are asking to lower the skill ceiling a negligible amount.
The great news is, if you "don't feel like" doing positionals, it likely wouldn't matter much at all, especially in dungeons since most of that combat is going to be AE.
That's generally why people are so defensive about it. Positionals give something else to think of in what is ultimately a somewhat simple ability rotation for these classes. People (I) would be worried that removing positionals from melee classes would make melee classes unfulfilling like ranged physical classes.
People who play at a "high skill level" need something to strive for and positionals are a somewhat simple way to give them something to strive for while not punishing the lower skill level people. So, whenever people ask for them to be removed, people get defensive.
