You said opinions can be wrong. I don't think it's worthwhile to discuss whether you mean it was up to you to decide or the mods. However, I'm going to focus on what this mentality does.
In practice, you end up fighting for a good cause, you and others dogpile members and eventually get them banned. Sometimes it's needed but sometimes it goes out of hand and it hits others who truly didn't deserve it. It is because you feel certain opinions are harmful or wrong.
And so, what kind of opinions are we talking about here?
Mothballs gave good examples of opinions that should be respected. Those are the kind of opinions I'm talking about. It'a unfortunate that members are branded as something extreme because they like certain games or a company just because said company happens to have done something reprehensible.
I hope you don't see me as trying to attack you. I just wish you can understand and that maybe you and, others like you,
can lighten up a bit and not always be in this mode.
