I’ve been using Linux for 19 years. In that time I’ve very rarely booted Windows.
If you don’t feel comfortable with Linux, then why use it? People who pressure you ir have an elitist attitude have always existed on both Linux and Windows, but they come and go.
The only legitimate complaint someone might generally have is Windows being a weak link on a local network, but in most cases its usually, even then, just someone trying to be part of the in crowd of Linux opposed to actually understanding what they’re saying well enough to have a reasonable concern.
Most people who become interested in Linux go through some kind of phase that involves talking crap about security or privacy or free software rights, but regardless of any of that being true or untrue, most of us just wanted to try something different when we tried it and switched after becoming addicted, then we go through our arrogant phase.
