I think unsupported malarky, and especially hypocrisy, need to be called out everytime they appear... no matter who voices them, or where.
When someone complains vociferously and repeatedly about OTHERS doing something they, themselves, are the most guilty of.... well... that needs to be addressed at every opportunity.
You can't just toss out accusations, lies, misrepresentations, and nonsense, totally unsupported by evidence or analogy... and not be taken to task over it.
The most import thing is the poll option of THINKING about what you read.
Knee-jerk reactionary name calling is not indicative of having actually thought about the ideas someone has presented.
