Looks like this immature brat doesn't understand the concept of "The Pen is mightier than the sword".
You are conflating people gravitating to platitudes with support for Democrat positions. Not the same thing.
Environmental concern is universally non partisan, that does not default as support for Democratic proposals like carbon taxes.
Abortion issues are 50/50 according to Gallup. There is no overwhelming support or consensus on issues such late term, tax payer funding state vs federal etc. The number of people identifying as "prolife" edges out "choice" out by a slight majority

Whose opposing healthcare reform? Democrats opted not to engage single payer when they had a majority in '08. When Trump eliminated Obama's "Mandate & fine" it was popular.
Republicans wanting to eliminate Social security & medicare is a lie.
Progressives have no recent record against a non interventionist foreign policy or being anti-war anymore. Clinton & Obama both engaged the U.S in new conflicts. Biden has supported every military campaign we have had since entering public life, his votes in the Senate have universally been in the affirmative and extended the Afghanistan withdrawal date past Trumps pull out. Trump was very aggressive pulling us out of Bush incs. wars, (that HRC & Biden voted for). Trump is the first President in my life time that did not engage the U.S in a new foreign conflict.
The two most prominent Doves in the Senate are Paul and Sanders, is Sanders a democrat this week? The Democrat party went out of their way to disenfranchise Tulsi Gabbard & Sanders who held classic anti-war foreign policy positions. Non interventionism is a classical conservative libertarian position, Both parties have plenty of doves & (to many) hawks.
We do have many "anti-democratic systems" because population centers such as California were never intended to lord over people in Montana. We are not a collectivist society and our government was designed to ensure individual rights in the face of collectivists and to maintain local determination.
Identification of platitudes does not equate to support for democrat proposals on paper, there is no policy monopoly as you claim on these issues.
