If you killed someone I’d have to cover up for you even though I don’t condone murder, if I had to kill someone to protect you I’d have to do it even though I wouldn’t want to.
Many parents wouldn’t agree with one, or either, of these statements. I imagine the fact he believes these has a big part in why he supports you, despite seemingly not supporting people like you. Some parents would turn their kids into the police; others frivolously argue a false alibi story. Some parents would disown their kids for choosing a career or partner or religion they don’t agree with; for others, that’s a bias-breaking experience. Some parents would die for their kids; others view them as labor or retirement security.

I presume you’re talking about the Flynn effect. Posts like these are usually based in Western Anglo-sphere nations, where the society as a whole is clearly getting dumber. Not shaming OP though - I feel all of this too as a USAmerican.
For the majority of the world, the last several decades have centered on expanding schooling of children, supporting women (half the population) in education, promoting small businesses of women, supporting small businesses in undeserved areas, and reversing the damage of colonialism.
The majority of the world has been steadily growing more intelligent as access to education has increased, and medical access has mitigated the toll of life on people. Undoubtedly, the USA and UK and many EU nations has been growing stupider, and supposedly in 2024 the rate had slowed to 1.2 IQ points per decade. It may also be that Western systems favor dumber people, but coming from the USA, I don’t think that those sociopolitical systems changed recently.
