I've translated the whole text contained in the afformentiod text book, not just the highlited part which is here in italics:
"Only a traditional family, love and the engagement of both parents guarantees children proper development."
"[...] Meanwhile, these afformentioned ideologists discriminate opponents by calling them names like "homophobe" or "transphobe". LGBT ideology usurping itself a designation of science, is in essence a derivative of the basis of Marx' and Engels' wrong theories. It is important to note the hostile aproach of LGBT advocates against religion and the church, which is exactly a derivative of Marxism"
I hate PiS, I hate PiS, I hate PiS :wholesome-agony: (or whatever the hexbear emoji is called)
ah yes, friedrich "homosexuality is a bourgeoisie decadance" engels has invented lgbt
death to fascists and traditionalists
ps: forgot to add but my family is what you call a "traditional family" and they did jack to guarantee "proper development" of me when i was a kid. honestly i feel like "traditional families" tend to be the most abusive most of the time.
