Actually, if I recall the majority of Democrats in Congress voted against the war in Iraq, even with the political pressure and disinformation campaigns being waged against them.
I don't have any idea what "expand the war in Ukraine" means, though. Russia attacked Ukraine, the rest of the world is if anything responding too little - in the 21st century, one country is invading and attempting to control another. That's insane and has to be stopped if possible. I doubt it will come to a lot, because nobody wants WWIII. What you're saying sounds like GOP/Russian disinformation intended to convince people to back away and let Putin win without resistance.
In general I hear a lot of Fox News talking points that have seeped into your thinking. Conservative thought is brain poison and contaminates the entire media and political process, even people who disagree with it. You are arguing points on their terms. Step one I think is to break away from that.
Roe v. Wade is dead because people either didn't vote or didn't vote for Democrats. This allowed the GOP to win elections they should have lost and pack the court. Whatever you think about the Dems, Roe would be fine except for all the people who bought into the "both parties are bad/the same" myth and either didn't vote or voted third party.
The "need to take a stand" bit totally misinformed - the left is constantly taking stands that hurt them. In particular, an agenda that includes women, people of color, LGBT, and the poor and middle class. Raising taxes on the rich? Cutting taxes on the poor? Stimulus programs? Medicaid expansion and Obamacare? Every one of these is a vote loser. If the Dems take any more unpopular stands, they'll be swept out and we'll have conservatives running the country for the rest of our lives.
Think how big a hit the left took on Obamacare - now, can you image what would have happened if they'd actually proposed "medicare for all"? Republicans would have held supermajorities in both houses after the next election.
The white working class is solidly Republican. Everybody says the Dems should "do more to reach out to them," but as of right now the agenda on the left will help them and the agenda on the right is killing them...and they're choosing Republicans. It's religion, racism, hatred of gays and love of guns that keep them in the GOP column. Unless the Democrats switch sides on those issues, it's a lost cause.
