:k:
true ! one must respect & do ahtram of the month of Moharram , it’s definitely not a shia sunni thing. I don’t now what point people try to prove by keeping weddings on 10th moharram and wearing flashy clothes , listening to music etc. Would you do all these things on the death anniversary of someone who was very close & loved by you ? I am sorry but if one can not have respect for the family of our beloved Prophet PBUH then I don’t think he is capable of respecting any other thing or anyone else.
and his mom was right on stopping him from going on 10th . Try to understand her reasons for stopping him.
