Disagreement is not calling those you disagree with "anol" or as having "OCD". That is being intolerant.
No, it's being descriptive. Sometimes people are excessively neat. It's a habit of some people, and I'm not talking about actual clinical OCD, I'm talking about being a bit of a neat freak. Sometimes people transfer this into games, and get annoyed when the game doesn't allow them to indulge their neat-freakishness. It isn't some brutal slight to call somebody a neatfreak, you know. Most people have been called much worse in their lives. Being tolerant means accepting people are allowed to do things, it doesn't mean you have to approve or else keep your mouth shut.
As I say, the OP put an idea out there, and so it's perfectly valid to critique it - and having the opinion that it's nothing more than an outlet for neat-freakishness is a perfectly valid opinion, and it isn't tactless or inappropriate to state that opinion.
If you don't like criticism of an opinion or suggestion, don't make the suggestion public on an internet forum.
