I didn't pick being a marxist and an ideology cannot be treated like a fashion statement as you've said. It also isn't something you can just pick and adhere to as if it's a club. And the "political compass" has always been a terrible "tool" (more so of a toy) to describe any leanings. You can't apply a label to yourself by yourself, someone else must do that for you by seeing you for who you are. I've been called a commie a few times, but most of the time people don't even know what a communist is or what they stand for. So I am able to talk commie to normal people (whatever a normal person is) without outright saying I'm a red and so I avoid their redscare conditioning and can have an engaging conversation.
You remind me of myself. I've been a "libertarian" too, not the popular type we like to make fun of here, but the guy you are describing as yourself. But I kept progressing in learning and educating myself, studying history and what existed in the real world, so applying dialectical materialism before even knowing what it was. It was until I've decided:
"Okay enough is enough, time to learn my enemy for who he is and what he stands for so that I may better combat him!"
And then after a while I've had my
moment. I've realized that everything I was standing for as this libertarian championing human freedom, expression, progress and development towards that in a scientific and realistic way was what the dirty pinkos were standing for as well. I've learned along that journey and the only thing left for me at that moment was to accept that I might just be a dirty pinko too. 
I wonder where you will end up, but please never tell yourself you are going to avoid certain material or knowledge just because you dislike the people behind that. Hell I believe communists must be studying fascism to better understand what it is and how to defend ourselves against it. For example I dismiss Mein Kampf not because Hitler wrote it, but because it's a shit work with nonsense inside. Largely a waste of time that will not help in understanding Nazi germany, a better alternative would be study Lebensraum and how it parallels to Manifest Destiny and such.
Learning about this stuff can not only help you develop but also prosper. I have hope you won't side alongside fascism, seeing as you already dislike whatever the fuck Milei is doing.
I’ll surely have those in future
Once you've realized that you can't join an ideology as if it's a club or fashion statement, you can't really adhere to it. You will stand out and be an outcast in said group, and among libertarians you are one. I know that because I've been that libertarian outcast too.
I wish you best, and I hope you stick around. Just be know the bears tend to be bullies as they've engaged with the talking points you might present a million times already. Hell most of us live in the imperial core, we engage with this shit on the daily. I suggest you engage in an earnest way to suck out genuine answers of who we are.
