Quoting the conversation you replied to:

Again, install Linux already and be done with this shit.

When Linux gets around to supporting all the games I like I will

Yes, the wording of "when Linux gets around to supporting" was bad and can be interpreted as "Linux needs to do the work". We who are familiar with Linux know that game support depends on the game's developer, not on any certain OS or plarform. You need to keep in mind that not everyone is as proficient with operating systems as we are, and thus not everybody might be aware who is at fault for lack of support.

You belittled the person in your comment, first assuming that they "suffer" on Windows, and then telling them to fix it themselves. You can't have meant that genuinely; after recognizing that they misunderstood the support situation, it should have been obvious to you that they're not capable of fixing the support themselves. So it must have been a snarky remark of yours and little more.

Instead of being this condescending, your comment should have been educational, explaining whose fault the lack of support actually is. Not even necessarily for the person you replied to, but for the sake of everyone else who finds this thread at a later point in time.

Even if you don't need Linux to win, I ask you that you consider how your comments reflect on the Linux community at large. What will people think when they see how you reply to people voicing their concerns?

Would you be happy being part of a community that although representing a genuine effort towards freedom from big tech, is perceived as elitist and insular by outsiders? I use Linux too, and I wouldn't be.
