What's wrong with capitalism?

Inherently promotes and incentivises individualist greed and infinite growth. Leads to unnecessary overconsumption and overproduction leading to environmental degradation, steers the culture to serve financial interests and consumerism leading to social-cultural degradation, increases economic inequality and the power of the most successful in capitalism giving them de facto political power, fails provide spiritual or social fulfilment even if it does increase material well-being, and not as meritocratic or eugenic as many perceive it to be considering usury and parasitism are some of the most profitable careers within it. Effectively, decadence is a inevitability in capitalism.

Are any of you socially liberal/libertarian?

No, I consider myself a social conservative/traditionalist (or social authoritarian or whatever you call it) more radical than anything currently in the Western mainstream. I see this inline with my belief in the concept of virtue ethics. I am so because I think that any civilisation of worth establishes within its social order a sense of discipline and collective duty. I believe this is actually a defining characteristic of our sentience, our ability to go above our animalistic nature to try mold ourselves into something greater.

This does not mean that I believe "no fun is allowed" or that there should be no individual free-choice, but there should be an acceptance of social harm as there is an acceptance of physical harm. Activities that undermine the social order which granted us these "sentient" living conditions should not be accepted. This also does not mean all traditions are inherently good, they should viewed through the lens of what they provide society and if indeed they are degenerative to a society they should be abandoned.

My opinions specifically on the issues you bring up:

• The actual biggest issue with abortion in my opinion is that it promotes consequence-free sex, further enabling promiscuity within a society. Although I also do regard feticide as a barbaric act, especially when done for selfish convenience. I accept their may be medical, ethical or "utilitarian" (I do not mean this in the philosophical sense) times for it. I would support a compromise that any libertine who gets an abortion should be permanently sterilised and so should the man who impregnated her.
• Gender roles are generally natural, biological sex is real and any social constructs regarding "gender" is built upon those realities to adapt as society gets more complex. A woman will never be suited for hard manual labour, but they will arguably be superior for example in nursing. Of course, I think some interpretations of gender roles are anachronistic such as the idea women should not work.
• Pornography is provably unhealthy for those who consume it and further enables promiscuity. It also is a parasitic industry that often feeds itself off the financial troubles of women (and sometimes men) in capitalistic societies with little social mobility. There is an argument that it may reduce sexual assaults though, which I think could be used if necessary as rehabilitation for perverts.
• Homosexuality is degenerate because a) it is not how human sexual interaction is supposed to be and anyone who does so is clearly defective and b) it is pointlessly promiscuous in that homosexual sex is not pair bonding between potential parents. I oppose any form of sexual-based pair bonding that is not between people who intend to be parents. I do not think homosexuals should be chased around though trying to exterminate them or something, support should be given to them to try live a life of celibacy.
