I evangelize Linux irl by simply keeping my computer always tuned up, up to date and working well. It’s inevitable that someone’s windows or mac shitbook will do something shitty and people will pay attention to me just for not having the same problems as them. For example the other day by brother wanted to watch spongebob, his macbook wouldn’t let him connect to the TV so I plugged it right in to Arch Linux and it worked like a charm. Sometimes the superiority of Linux simply speaks for itself.
