I didn't watch the video but people are going to switch when they're ready. It's like smokers, you can't force them. Just be open about it if they ask and they might gain interest in it. Don't be too overbearing and be open about the issues you run into when they happen. Remember both Mac os and Windows can be buggy and frustrating at times too.
My mother wanted to switch when she learned that you could play games on it and saw me use it for a week give or take, so I helped her. She's happily using fedora on her desktop and Linux mint on her ancient laptop now. Oddly enough gnome is less confusing than cinnamon to her. Maybe she's just use to the smartphone layout.
So supportive, I love it!
The whole thing isn't my cup of tea. If anyone else wants to be a femboy, no judgement from this corner. I say be what you wanna be, life's too short to worry about assholes.
