Of course you're allowed to have preferences and talk about it. I encourage you to do so, I love talking about this stuff and I love seeing people do the same.
But it's really tiring when the conversation, 100% of the time devolves to KDE users hating on Gnome for zero reason. As if there's only space for one DE and having a choice in the matter is wrong.
If you don't like Gnome, just don't use it. And try to accept that just because you don't like it doesn't mean it's wrong.
Trying to equate Windows being a default with Gnome being a default is crazy and you know it. I'm not even going to bother explaining why, it should be so obvious.
KDE is the default in plenty of situations too. It doesn't mean it's forced either.
I also never said you should be homeless or uneducated. Please don't lie. All I said was that you aren't forced to use Gnome. Because you aren't. You're lying there.
Nobody is forcing you to use Gnome.
