For a lot of distro’s you don’t need to use a terminal to install things if you aren’t comfortable with that. While I believe learning to use a commandline a little bit will always be beneficial, you really don’t havo to. Take a look at linux mint for example, which has a “store” for packages.
I think the phrasing is the problem. This comes off as overly negative. If you say something more along the lines of “I am not yet ready to have kids, so I’d rather not be with someone who has them. I like women who are in good shape, and I am looking for a long term relationship.” You come off as way less of an incel.
