First off, let's preface this by going over the etymology of the words "liberal" and "libertarian". Both words stem from the word liberty, which means freedom, and within the context of politics the freedom of not being burdened by authoritarian regimes and policies.

So with that out of the way, let's break down your references one by one:

>His vicepresident has strong ties to the military

This has nothing to do with liberty or even politics, this is about power. Both the left and the right want the military on their side, lest they suffer a military coup and lose power.

>opposed abortion rights

On the opposing hand it's the freedom for a newborn fetus to a prospective life, and on the supporting hand it's the freedom for a mother to do with her body as she pleases. Either way, abortion rights is a question of who's freedoms are being guaranteed and thus liberal/libertarian in nature.

>[opposed] same-sex marriage

This is squarely authoritarian and is in opposition to liberal and libertarian politics.

EDIT: It would appear this claim was made in ignorance or bad faith, so I'm striking this part out.

>[opposed] feminism in general

Assuming that "feminism" here actually refers to the phenomenon and movement of certain people wanting women to be more equal (read: more powerful) than men, this is guaranteeing the freedoms of the individual regardless of their gender and thus their equality.

>publicly denies climate change

Imposing policies based off nebulous scientific models of questionable accuracy and encouraged by pundits of questionable motivations is authoritarian.

>is against gun control

Guaranteeing the people's freedom and right to bear arms by opposing top-down regulations and policies is squarely liberal and libertarian.

>and a large government

See above.

>He is not only economically but also socially on the far right of the polítical spectrum here.

Seeing as Milei is in favor of liberal and libertarian policies, and seeing as the left likes calling themselves liberals, Milei is quite correct in saying that he's only considered "(far) right" by virtue of the left labeling everything they disagree with "(far) right".

Just to add something to this discussion - South America is fundamentally different from the US. The region has a long and terrible history of gang violence, political and military coups, drug cartels, etc and so forth.

The last thing it needs is more guns in circulation.
