On a grand social level, most left leaning people would prefer no easy access to guns. Other countries have succeeded in this, for their own reasons.

In the United States, the people targeting minorities have guns. Minorities buying guns is self defense and a reaction to increased persecution.

Other left leaning people who are normally against guns recognize that oppressed minorities are less likely to commit hate crimes with them(especially against people that support them), and more likely to use them for defense, as a deterrent, or for radical action against oppression.

Honestly, left leaning people (like myself) currently saying stuff remotely pro self defense using guns is more an expression of hope of arguably evil people (read: ICE) being shot than actual belief that this is likely to happen on a broad-scale.

This is for at least these two reasons:

1. For a variety of reasons, minority groups that could currently have use for guns for legitimate self defense are the ones who overwhelmingly do not have guns. As someone from a country with sane gun laws, I consider it relatively straightforward that having more guns is not the solution to this, also, see 2.
2. Shooting someone from the government coming to kidnap will not really prevent you from being kid napped for longer than a few hours, maybe days. The state out-arms you as an individual significantly (which arguably is not a bad thing), and this has been the case for over a hundred years now. Meaning: the actual effectiveness of guns for self defense against state violence is near zero for the individual.

On a systemic level, it would however improve the status quo if there were notable risk for ICE agents to kidnapping people, i.e. being shot. This is probably not gonna happen for the aforementioned reasons. You can (and we do) still have hope though.
