Heavily depends on the subject. Of course trying my best to be reasonable person, then many opinions can change over time due to new information or perspectives. So if you specify a subject, i can give my perspective on it and feel free to counter it, as it's rather useful in testing out and refining opinions/perspective.
In general, live and let live(with some exclusions), just try not to make the surrounding area worse than i found it. Sometimes it's even possible to leave it slightly better than i found it. Similar applies to people, while i might be an asshole(ASD, social difficulties) with a fucked up sense of humor, i do try to be helpful and try not to be purposefully malicious(abuse/take advantage/hurt) towards other people.
Some of the more controversial ones: Supporting transhumanism, leaning towards cybernetic augmentation of the human body, but as trans people fall under the same umbrella they get my support as well.
Regarding food: food is just fuel. There's minimal emotional component to it. Daily eating is just another chore to maintain this biological meatsuit. Efficiency to get in a somewhat a balanced meal is the primary concern.
