Too harsh? That probably depends on the motivations of the poster you were referring to. If he intentionally ignored the psak of the gedolei haposkim, then he deserved to be rebuked. If he was unaware, then it was too harsh. I’m curious how you knew that some links were deleted. Was it posted and then removed, or do you have inside info? It seems hypocritical of that poster to want to debate the topic without links, yet provide links.
The second part of that post was also interesting.
