Yes I agree with the argument, "if it's not for you, don't join in" Quite a while ago, someone came on the Genealogy thread, with the comment "can't understand why anyone's interested in this" fair enough, not for everyone, but when I started doing family history I found some strands of my family history I uncovered among the most exciting discoveries of my life. Sewing and similar activities don't interest me at all, but I certainly wouldn't go on to a thread on the subject and say that. We are all different.
Also some threads are just to have a chat, lighthearted and myabe to introduce a bit of levity, or to have a moan, maybe to take some posters minds off serious worries they may be experiencing.
