I personally don’t go to concerts because I think concerts are boring. I do enjoy ball games but in any event it’s not the same thing as (besides for the obvious) I’m in a comfortable seat and my presence actually matters because without fans, the team is worth nothing.
The only think I remember enjoying from the siyum hashas were the stories in the speeches and the powerful amen yehei shmei rabba with thousands of people. I do remember being bored the rest if the time.
However I don’t see how any of this is a comparison to simchas Torah. On simchas Torah either 1) everyone deserves to celebrate equally because we’re all celebrating the same thing or 2) only men are supposed to celebrate because only men earned simchas Torah so the women should be happy that the men let us stand squashed and claustrophobic against each other while we get to watch what they earned knowing that we didn’t earn anything or 3) since a woman’s job is to be the encourager of Torah while not actually doing anything herself, also today she is supposed to watch the men do the ‘we are proud to be Jewish’ dance but shes not actually allowed to do anything other than watch the true heros express their feelings bec her role is to be an enabler but not to be Jewish.
Btw to satisfy number 1 I would be happy if there were a kumsitz. It doesn’t have to be the same as the men nor does it have to be in the same place as the men.
