Ugh, there isn't anything adversarial about memes - and to say otherwise is to accidentally admit a lot more than you likely intended. They propagate for the same reason that stereotypes do: they're useful.
The memes themselves needn't be "adversaries" for it to be to the benefit of one of them to inspire rage against the other. "X makes people angry at people holding Y" can help X spread because people like talking about things they're mad about, and the presence of Y actually makes that more effective; the memes themselves are, to a degree, symbiotic within the broader society even as they maybe do bad things to the people in that society.
For one particular perspective on this, I enjoyed https://www.youtube.com/watch?v=rE3j_RHkqJc - relevant stuff starts around 3 minutes in.

It isn't difficult to guess at what other defining characteristics you posses once that is established.

Why are all your comments about Europe though? You sound like you've been radicalized. Get off YouTube and stop watching Alex Jones, I'm saying this for you own mental health.
