Probably. But that is off topic. Replacing objective debate with personal attacks is a sign of weakness. I also consider it abuse of communication for the purpose of winning debate. Please don't abuse communication to win your point.

There are rules that don't need to be broken in any debate and those who break them only show weakness of their point of view and reduce efficiency of a debate.

One rule is do not change subject unless it helps you to objectively prove your point.
Second rule - do not put words into somebody's mouth. Don't assume, just ask.
Third rule - do not debate about intentions, debate about facts.
Fourth rule - do not joke without explicitly indicating that this was a joke. Joking can be used to conveniently back off wrong opinion without losing credibility, not that credibility matters much in objective conversation anyway, but it adds noise and waste of time.
Fifth rule - do not ask questions before getting answers on previous questions assuming how those answers will look like.
Sixth rule - do not interpret timing of response as part of an answer. Don't interpret silence as agreement or lack of knowledge.
Seventh rule - do not lie. Everybody can be objective about a subject even if their stakes are being hurt by discussion. It is not true that people have opinions based on their stakes. If discussion hurts your investments, just don't participate and if you do then don't abuse and don't lie.
