It really doesn't require much study to understand and promote. You can go as deep as you like, but the underlying principles are straightforward and rather obvious, like class dynamics.

Additionally, Capitalism doesn't have any "edge" over Socialism - it's in a steady state of decline, has been declining, and appears to continue to decline. Capitalism cannot be permanent, it does not have a head start, and there is no need to force everyone to understand how Socialism works.

That's really my point, you have these knee-jerk reactions because you are unfamiliar with the topics at hand, and do not appear to have tried to understand them further. The inevitability of Capitalism's decline means you don't need to be forced to understand Socialism by anyone, you'll either learn on your own or will ride the tide.

You probably won't agree with what I have said, but that's more a choice you personally make, on whether to engage or disengage, and that's fine.
