Masochism

I have no idea what it is, please enlighten me in depth! Preferably in a closed setting where any bystanders cannot leave .

I will also need an explanation why Windows is bad and why I should care about online privacy.

I've heard that hackers use Linux, will that make my printer be susceptible to hack so China or CIA can see my bills that I print out every month?

Absolutely not

(Tbh, I think any reduction in meat consumption is good. You don't have to be a purist to make a positive impact and if people really cared about animals they would ostracize others for not being vegan 100% of the time)

If you care about animal suffering, remember not all animals are the same, there is a continuous line of intelligence between some grass and a dolphin, you have to decide at what point you value. Pig? Chicken? Egg? Insect? Salmon? Sardine? Fungus? Starfish?

From my understanding, cutting out most mammals from your diet would cut out most of the more intelligent animals you eat. (Unless you eat crows or octopus)
