I say this for the sake of other teachers out there:
To say that something is Halacha and only later, upon being asked, to elaborate that it is the opinion of SOME poskim (and not to say whom), seems irresponsible and misleading to me.
That’s like saying “in the name of some, you have to keep this Halacha”.
If you are blessed to know how to spell, than please use your gift also to not hurt people. A joke is only hurtful when it’s said to make fun of a person.
