It's common for reactionaries to say stuff like that. For many of them, Jews are considered inferior but are believed to control the world. Trans people are statistically such a small minority that we don't matter, yet for them, it's an ideology so dangerous that it's seen as a craze that's corrupting all children in school. The thing about imagined enemies is that they dont exist, and fascists can make absurd claims about them.
lack of philosophical rigor and intellectual dishonesty allows you to bend concepts at a whim and make up stuff, so they used that to throw shit at every direction and coopt the maximum number of people. like you said with straw men that contradict one another.
Most welfare recipients in the US have a job. "Welfare means you don't have a job" is myth perpetuated by those who'd like to see welfare programs cut.
I once saw someone claim that immigrants are being paid to come here by WEF/The Jews to disrupt the west. But that conspiracy doesn't make sense out of the gate because whose being paid? The people going to Europe are all poor and can barely afford clothes. Those people have secret piles of money they aren't using?
Usually the conspiracy theory is that the JEEEEEEEWS are bribing politicians to sit on their hands purposefully, along with paying the smugglers that transport the people so they invest more into their operations.
