Why don't leftists seem to be interested in things like opsec, firearms training, small unit tactics...

Those are left communists

organizing is hard when liberals get on the way
Some people is organizing and developing a movement but still liberals are an obstacle
You start a socialist org, a liberal arrives and tries to take down anything class related

Holla Forums is not the same as fedbook, it is an appropriate place to promote a real understanding of OPSEC. It's not a place to discuss real plans or anything, but general tactics and security principles are fine to discuss here.

OP, the reason most Western "leftists" and even "communists" have no security discipline is because they are rank amateurs, opportunists, adventurists, and idealists. Lenin wrote extensively on the need for secrecy and professionalism in the socialist movement in many of his works. I recommend What Is To Be Done and Left Wing Communism An Infantile Disorder for an intro to his thinking on this topic. All serious modern revolutionary groups, communist or otherwise, from the IRA to Hezbollah to the Naxalites, adhere to strict secrecy and discipline. We should study the old tactics of groups like the Bolsheviks and the PLAF, as well as the modern tactics of the aforementioned groups, and seek to emulate them while adapting to the present situation.

Three things everyone should learn from Lenin:
1. Legal and illegal work should be mixed together. If you are a communist in a Western "Democracy," it is easy to fall into the illusion that promoting communism is not an illegal activity and won't get you arrested and killed. If your communist group organizes while making this kind of error, it will totally crumble when the new Red Scare happens. Therefore, communists must mix their "legal" activities with activities that are definitely illegal (or at very least heavily suppressed, even something simple like advocating for imperialist mercenaries to mutiny or desert) and conduct both with the necessary precautions and mitigations.
2. Propaganda, through agitation, newspapers, or modern media, can often be the most important activity available to communists due to its appropriateness in all contexts. The vast majority of the time spent by Western communists will be downtime when there is no revolutionary or even strike potential, particularly at first. Therefore, while the appropriate training in weapons and tactics should be undertaken, forming militias right off the bat and marching around at protests with ARs and AKs is blatant adventurism and likely a honeypot. Development of a comprehensive and effective propaganda apparatus to counter and dismantle capitalist and imperialist lies should be the number one goal of communists right now.
3. Security is not perfect, anonymity is not always possible, in order to engage with the masses, communists must take some risks. Any modern OPSEC expert will tell you that OPSEC is a constant process of mitigation, compartmentalization, and active response to breaches and infiltration, and Lenin was perfectly clear about this in Left Wing Communism An Infantile Disorder. "Le anonymuzz haxxer" activity is not only not correct communist praxis, it is a pipe dream as evidenced by the ridiculous level of FBI infiltration of Anonymous and Occupy (to the extent that these groups were basically honeypots and FBI puppets from the start). Real revolutionary communists will be secret where appropriate, take risks where appropriate, and have a backup plan for their backup plan for their backup plan.

And yet, no one ever links a source or PDF of any of this? got any?

Source that these groups maintain secrecy and proper security measures? I mean, that's obvious if you know anything at all. Or do you mean actual research or materials to learn from? Well, what I am saying is we need to do the research. I intend to get around to it some time, but right now I am in the middle of Captial. I invite you to do some investigation of your own though.

Because we hitched our wagons to the liberals back in the 60s and 70s to form the so-called "New Left" and have been riding this shit downhill ever since.
