Is it normal to stand up for what oneself believes in?

Changing the subject from my previous posts I kept it simple and decided to ask a normal question: is it normal to stand up for what you believe in?
As a poshie I stand up for the belief in respect to my poshness even respect for the fancy food I eat (which I sometimes get from my parents), I was forced to add an extra rule to my code: assertiveness, when my mother cooked me crap I no longer eat, not once: she cooked me a normal salad and ordinary Italian pasta and tomato sauce instead of a salade nicoise, I got angry and threw them on the lawn and said "this is crap! This is rubbish!!!", and when I said to Mum "it's not even fancy" she said "who do you think you are?", I know exactly what I am: a fancy man, that means she has to serve me fancy food, not the other way round. I refuse to believe my mother or anyone can't be reasoned with, rationality's good in every way therefore we can all be reasoned with. It's not extremely difficult, it's usually effective and mind you Mum can only be reasoned with by being yelled at with a simple request and that's it, without syllogisms or fancy explanations used in reason. The same way David the client where I live can be reasoned with that way, hence he asks permission to switch the light off. As an ableist I told him he's stupid and dimwitted (because he has a disability) so get lost I said to him. Furthermore I learned to hate and I learned it well: misogyny, misanthropy, pessimism, solipsist pessimist (I don't interact), and ableist, hopefully the type of mentalist who hates mental people in general (I've done all the above beliefs for a long time). And furthermore I asked for where I live quasi-vegan gourmand gastronomical purist food in the shopping: fine cheese, caviar, water crackers, fancy salami, silverbeet, spinach, tofu (that's hard firm tofu), unsweetened plant milks, wholemeal bread galore, mushrooms, and so forth (all related to what's at least quasi-vegetarian). They said they'll buy for me what I requested in the shopping list, only when I see some of it, if not all of it, will I believe it. So even in that instance I stood up for what I believed in. I have a 'Plant Eater' sweater (maroon with green writing), and a 'this is what an atheist looks like' shirt, and what makes any kind of vegetarian or atheist so special is quite simply that there are things from shops to cater to them. You hardly get anything special for normal people that says "normalcy" written on it do you? But I think if it's special for normal people it should simply be normal clothes. On the other hand I joined communities online based on what I believe in: vegetarian, science, misanthropy, demonology to name a few. I even made such a war to get whatever was vegan printed for me, there's nothing vegan without a fight, without a struggle. However I also am partially a liquitarian, therefore I have liquitarian drinks, I went out with a vegetarian and, based on my tastes in food, decided to ask for coffee I merely call froth (which isn't on the menu) and got what I asked for, which, without chocolate sprinkled on the top, is very fancy and very exquisite. Any of this normal? Just asking.
