While i don’t agree with Haimy’s style or approach (and am choshed that it was written like that for that reason), i find the responses embarrassing.
I completely agree with the responses, but you have sadly strengthened his point. Had someone written an overdramatic post on lashon hora or fraud you never would have asked if he feels the same about mishkav zachor. The appropriate response would probably be to add it to the offenses, not to use it as a counter argument.
I spent too many years working in a very very liberal environment where straight conservatives were the minority. I respect my coworkers but was apalled by their lifestyles. But it wears off. And i left because of the effect it was having on my spiritual level.
Do i think Haimy’s approach is effective? No. And i doubt he does either. But the responses, though accurate in content, were inadequate in context.
