He's been hardcore-brainwashed by the blue pill conditioning.

If yes, how should I proceed? what do you guys recommend?

If no, why not?

Thanks in advance.

edit

I should give some context:

I guess I should give some context about myself too, at least briefly, I'm in my late 20s, swallowed the pill like 5 years ago, struggled because I grew up with practically both of my parents absent, raised by women in my mom's family (yeah, nothing new I guess), but made a fucking lot of progress, and basically I just want to keep improving.

Coming back to my dad, he's still married, thinks men and women are mentally equal, and because of this and other several blue pilled thoughts alike, he's not doing well with mom, his marriage's been slowly coming to pieces for the last 20 something years, and he has done a couple (several) horrible financial decisions (like giving away a HUGE cash amount to some bitch he was side-dating... yeah, cheating. The bitch obviously doesn't give a shit about my dad's wellbeing, but my dad thinks she's some kinda fucking unicorn, he's blinded by the pussy and he thinks she deserves to be "helped" just because of "love" or some bullshit like that).

I haven't said a single word (yet) to him, besides the occasional discussion with differences of ideas, where he immediately disregards any view because he can't stand his cognitive dissonance when faced with any concept that doesn't fit his blue pill narrative. So I primarily keep the discussions brief and I avoid trying to convince him of anything.

One day my mother confessed me that she doesn't love my dad as a man anymore (she used different words, but that was the idea. She doesn't find him attractive or manly or "an authority worthy of respect" anymore, though she still respects him... just for the sake of "humanity", that's what she said). I know I shouldn't be interfering in their marriage, it's not my business and it doesn't affect me in any way, but it kinda hurts to see them just slowly but steadily falling apart. I mean, he's my dad.

So, I don't really know if I should introduce him to The red pill, because I personally think that it's useless to cram any kind of wisdom into another head if they're not looking for it. It's kinda futile, I think that the search for knowledge/understanding/whatever must come from one's inside. Else, it's as useful as listening to the rain.

What do you guys think? Should I let him be? or should I introduce him to TRP? if the answer to the last is YES, then how should I do it? do you recommend anything?

edit 2: a commenter asked me if my dad is happy, well, he's not happy. He puts on a mask of happiness and maturity and understanding, but he's confused as fuck and he's full of fear, and I don't like to see him like this. Despite his bad parenting and any mistakes he could have made, he's a good man and he's my dad. I want to lend him a hand but he doesn't listen. I just don't know how to proceed. Sometimes I think the healthiest thing I could do is just to let him slowly die, but I don't want to keep my arms crossed IF I can ACTUALLY do something to help him.
