Are there subjects you don't discuss because you don't think they deserve air time?

There are debates I don’t engage in because I think that to do so gives credibility to positions that don’t deserve it. Some issues are transparent to logical thinking, and the opposing view only represents hostility, or alarmism™. I won’t give examples; I expect you will understand why.

Are there discussions you will not engage in for similar reasons? (And no, I don’t want you to name them!)
