Think about it, no other series of movies have ever had so much latent and hidden symbology and subtext, I mean it was so much that it became a publicly know thing even with NPC's...
edit: when you are good and have a good message but live in a bad guy world, trying to have obvious goodguys deliver that good message is likely to fail to the point of the message never even getting close to being spoken..
If you however use the bad guys and let them think they are making a hidden bad guy message, many things suddenly become much more possible.

The lefties have to project their own evil on to the their bad guys. They can't cast the true conservatives in a bad light because it's not bad. It's very weird now that I think about it but they have been doing it to Trump and now us, so it makes sense they've done it in the movies.
