I do support the basics of Libertarianism, but I can't support the extreme-versions of it left or right sides.

American "libertarianism" is a correct identification of the issue with oppressive use of force by the state, coupled with a somewhere-between-ambiguous-and-incorrect interpretation of when force is oppressive and when it's not. It's my stance that American libertarianism (based on the NAP definition) with a properly calculated ethical interpretation of justifiable "property" simply reduces to anarchocommunism, as many unexamined assumptions about when a "property" claim is justifiable and when it is not simply accept a capitalist market economy, and any inequality that may result, out of sheer laziness. A lot of people find this way of looking at it jarring, usually because they just try to cram it somewhere on the "left/right" scale without really examining each ideological underpinning, or by really examining the range of thinking within the space. And some of that results from fascist groups trying to coopt the label as well. Good litmus test for that is asking a self-identified "libertarian" what they think about immigration, or the justifiability of a given war. The "MAGA LINO" types will justify immigration crackdowns and wars, the dyed-in-the-wool "libertarians" will oppose them, and so on with other oppressive policies that leftists also oppose. Which leaves the main point of contention being how the economic system works and how property distribution works, something which the "NAP" is ambiguous about. Therefore...

Sounds great on paper, in practice it’s almost entirely old white men who want to get rid of age of consent laws or people who want to be able to do insane, dangerous to others shit like feeding bears without anyone being able to stop them.

In summary, the ideology of selfish jackasses at best and pedophiles at worst.

I think Libertarianism is incompatible with the way that humans operate as a society. Almost all flavors of libertarianism puts an individual's right to live as they choose as long as that doesn't violate the rights of others through force or fraud. Humans like to associate themselves into groups, and in almost any group there will be an imbalance in power, whether that's economic power, physical power (strength), or even something as abstract as eloquence or how outgoing you are. The issue then becomes that someone somewhere has to enforce the right to not be forced into giving up rights. In the classical construction of how libertarians view government, it is very easy to become more powerful than those meant to enforce limits on power. Even in our current political system, you see this when companies will spend more on their anti-trust court cases than the entire FTC spends total in a decade. Libertarianism has no mechanism to keep the enforcer the most powerful party involved

Either incredibly selfish /self centered people, incredibly uninformed on the real world, or a combination of both.

Pedophiles trick children into thinking they're libertarians because cops are bad and weed is good

afaik it was originally about freedom from oppression. as with so many things, it has been hijacked by bigots and they've twisted it to now mean their freedom to oppress others.

Anyone I've ever heard talking about the non-aggression principle spat red flags faster than a machine gun.

At best, they're truly so dense and unsympathetic they don't recognize actions that aren't directly or intentionally causing harm do still cause harm (example, the free state project people leaving food out for black bears "because they can" without thought for their neighbors who then have to deal with more bears). At worst, it's rape apologia (crap like statutory rape doesn't exist because that minor "totally asked for it" and the rape didn't cause physical damage).

I think it's nonsense.

The "free market" is never truly free, and if there isn't something holding the capitalist class back, they will always dominate the working class until the system just breaks. The only way for a stable society to exist is for checks and balances.

The best right wing libertarians end up being left wing libertarians.

It's dumb.

Works wonderfully if you're profit. The free markets love you and will do anything for you.

Oh, you're a people? Have you heard of our Lord and Savior profit? If you're not helping profit then you must be hurting it, therefore hurting the market. We don't take kindly to the likes of you.

It is an ideology for selfish amoral oppotunists
