You might want to (re)watch Star Trek TOS. Glaring in my mind is The Omega Glory where Kirk reads off... well, spoilers: it's absolutely a political episode (as is most of Star Trek) and it rather killed the episode in my opinion.
But this new generation of Trek seems to have completely lost that ability, while at the same time retconning large parts of the universe, and its inhabitants, to serve it's now much more simplistic moral dilemmas.
Which becomes particularly apparent when contrasted with something like The Orville. Sure, MacFarlane's humor can be an acquired taste, but I found that comedy take to be much more relatable, and truer to the "Trek spirit" than recent Trek offerings.
Maybe that has to do with the fact that The Orville also depicts a way more optimistic picture of future humanity, akin to the old Trek, while new Trek seems to be too busy to make Trek as gritty, edgy and actiony as most other media nowadays.
If we don't see the original Star Trek as staking as many firm moral positions on issues where popular opinions are mixed, it says more about who we have become today, and how popular morality has adjusted, than about what was or wasn't radical or confronting at the time.
There doesn't seem to me to be any plausible claim that earlier Trek was previously less "confrontational" or deliberate in promoting its chosen morality.

Gone is the attempt to tell good stories and now we are stuck with political preaching which always requires all the canon of the show or movie being used to be trampled if not insulted.
RLM pointed out the defining difference between Gene Roddenberry's Star Trek and all the tripe we have today. When he wanted to deal with race he had the characters blow it off, it was such a non issue then they could not take offense because it did not occur to them. (episode with Abraham Lincoln)
Instead we are served the tripe and hatred that the woke political movement uses to silence those it does not agree with or those who dare call them out.
