Yes, You Can Love and Adore Things Whilst Also Criticising Them
Criticising something and disliking some things aren't opposites (as concepts/attitudes). There are famous sayings along the lines of, when you stop criticising something or give up offering ways to improve, then that means you've given up on that something (or someone, sometimes). The idea that you're attached to something is key. If you care about something or someone, then you'll very much care about the destination of that something or someone, right? If you quit caring, and thus quit criticising, that's not the same as acceptance. It might even be a sign of apathy, maybe rejection.
There are all sorts of projects and companies that we criticise here all the time. Criticising is OK. It ought to be welcomed sometimes. I too read criticisms of myself, my sites, my articles. I view some of those as constructive and some as mean-spirited attacks, depending on who or what does the criticism (which implies the "whys").
Decades ago (maybe too much yearning for the 1990s, that's a giveaway) we were able to disagree with people, even in the open. Even with employers! On many occasions I openly criticised my bosses, sometimes to their face (even as a teenager). Before I quit Sirius I confronted my bosses for a number of years, preferably over the phone (where making excuses and preparing carefully-crafted lies would be harder). E-mail criticism was easier to deflect, in my experience.
By 2022 it was already becoming very hard to criticise bosses. Doing so was feasible, but they would just not listen. Lots of that foolish, infantile, "either you're with us, or..."
Regarding politics, which isn't our focus in this site, back in the old days we could argue with people - even close colleagues - without words like "Woke" or "communist" or "fascist" being tossed around.
Is society being divided and groomed/primed to be resistant to constructive criticism?
For what it's worth, it's OK to argue with BSD folks (the operating systems or the licences); it's like brothers and sisters having arguments. Our overall goals are pretty much the same, even if not 100% overlapping. A lot of our "blood" (code) is also overlapping, as we stand to benefit from kinship. Opinionated people can have fierce arguments with siblings and parents and still love them deeply. █
