Dog whistle literally just means coded language that an ordinary observer might not notice, but can be used to subtly identify other like-minded individuals.
Not all dog whistles are necessarily bad (depending on perspective). I'm an ex-mormon, and one dog whistle is a tapir. Without more information, it is too subtle to really know for certain whether I just like tapirs, or that I'm actually ex-mormon. But eventually, two ex-mormons might see enough signals to finally confide in one another.
A lot of the language you used is innocuous enough, and I didn't feel like it was at the level @hoodatninja claimed, but it definitely had a "Reddit was becoming too woke" vibe to it, without actually coming out and outright saying it, aka, a dog whistle.
