EXACTLY the wrong advice.
Screaming socialism is what works. Screaming Marxism at universities is exactly what has caused the issue, or do you really believe that there are more facts supporting socialism today, than in the past (the case looks worse and worse as each year goes by). There really is no intellectual battle, everyone with even an ounce of intellectual integrity knows socialism is a lie and a power grab.
There is no point in arguing against someone with facts when the only thing they understand is rhetoric. Most of the Marxist indoctrinated people physically can't even think logically, about anything.
Do you think the tactic of just screaming SOCIALISM! is working?
Do you see our society moving right?

The tactic used by the right has not been that of smear, but reason. It has failed. War is not won by good arguments, but guns.
Now, the left has used only smear and corruption, that has actually worked. It's almost ironic that the left understand human behavior better than the right when it comes to actual practice.
From my perspective - and yeah, I could definitely be off here - the Left has enjoyed so much social/cultural success for two reasons:
First, it has been consistent and methodical in its approach for literally decades, generations now. Example: Look at how the power of PC and Identity Politics slowly but steadily increased at the core of our society, until now a person's skin color or sexuality are forefront in who they are and how they are to be treated. That didn't happen overnight.
Second, the Right simply did not see this building until it was too late for them. Now they're trying to wrestle the society back all at one time and they don't know how to do it (neither would I). So the approach I'm talking about would be more patient and deliberative. I don't think they can make this change all at one time, it won't happen overnight.
We'll see, but right now the momentum certainly looks like it belongs to the Left.
