Let's take the obvious "Pro military for defense" first since that's the most insane thing to think is a contentious political issue.

There are 30% of people in the US that think aliens are real and have visited their asshole but you will not find 5% of people in america that oppose the military as a concept.

What you're doing here is being manipulated by people who want you to think some of these things are Important Issues(tm)

The trans women in sports is a great example of propaganda. It was cooked up by a conservative think tank. How many people are affected by this "problem"? Maybe 200? And in most cases sports organizations themselves often have rules in place like "how long you'd have to have been on hormone therapy to qualify." That is already more or less a solved problem for most the people it actually affects. People playing sports didnt come up with the "trans people in sports issue", a think tank did.

So what you are ..is manipulated by think tanks and propaganda and in a way that causes you to oppose people who otherwise have common interests with you.

There's only two real political philosophies and they can be summed up as "fuck you, I got mine" and "we're all in this together." I will tell you right now only the "fuck you, I got mine" group has any real interest in dehumanizing people by say, having the government ban trans people from public spaces and public activities like sports.
