The Marxist / social democrats know that if they admitted their ultimate goals, they'd receive substantial pushback. As a result, they need excuses, however flimsy to justify their work toward undermining our country.
That's why they claim that gun control is needed to fight crime, when they know that only law abiding citizens are effected by gun control. They claim that they want to protect kids against bullying by instituting CRT, and other leftist indoctrination into the schools, while they actually encourage bullying, and abusive behavior.
They get to do their dirty work under the cover of barely adequate excuses. And it works.
