No, Marxism is reaping all kinds of damage in some parts of the country. And in certain Marxist strongholds, especially among certain demographics of those cites, that damage manifests itself as violence committed with firearms among others.
...and that governments there ought to be able to license and register handguns if it makes streets safer.
Whether they ought to or not, they have. And the result has been without exception to create the most dangerous ares in the country.
ares = areas
I recall reading, though I haven't found a proper cite, that the notion of a single woman being allowed to demand child support is comparatively recent, and was imposed by judges rather than legislators. I strongly suspect that notion has done more damage than almost any other, since it served to grant legitimacy to the concept of single motherhood.
IMHO, unless a mother is in a position to support a child without the aid of money forcibly taken from someone else, giving the child up for adoption would in almost all cases be better for everyone concerned. Allowing the mother to demand child support from the father will encourage a course of action which will be to everyone's detriment.
