It's shoving down throats when Linux is brought up in every single Windows discussion. The complaints about Linux are in response to Linux users never being able to just let it lie, people aren't just bitching in a void.

This is absolutely not people being mad for people just talking about something. I have an extremely hard time believing you truly believe that is the issue here.

There are countless places to discuss Linux without bringing it into the comments of every Windows post. Windows users are not commenting on every post in the Linux communities about how much more straightforward running Windows is.

It would be like vegan eaters commenting about how good it is to be vegan on every post in food communities that features non-vegan food.
