The seriousness of a given issue will depend on the group in which it is raised, and that does not mean that it is not important. It will be relevant if it interests and benefits me, otherwise it will be relevant.
We cannot denigrate others for not giving importance to the serious topics we raise or participate in; for sure, you would feel “out of place” in a religious chat and that does not mean that it is not serious and important.
Everyone is free to use his or her free time for recreational activities. My brother, for example, enjoys playing dominoes, but he hates chess, which is the game I love.
