I just released a video talking about why I don't do Linux "evangelism". This is part of the ever growing "Boomer Rants in Woods" series.
I detail why in the video, but it ammounts to two main points:
The "solution" to these constraints is simple: if you want to get people to be more open to Linux, show them what you can actually do on it. This solves both problems.
While I certainly don't have my channel for Linux evangelism, I do feel like the channel has approached doing just that as time has gone on. I don't talk conceptually about Linux or *nix generally unless it's after showcasing some feature or explaining the efficiency of a design. This encourages people to actually understand Linux, how it's different from their common experience and encourages them that they might benefit from using it.
