Indeed. It is if you completely ignore the initial criticism though. That’s kind of the point.
It's not ignoring the initial criticism.
It's pointing out the purpose and intentions of raising the criticism, which is often to denigrate the subject as being something heinous, in order to influence others to oppose the subject as well. Yet at the same time, are fully aware that from their own side, usually to make a moral comaprison of someone/thing they advocate i.e.
"at least the person I advocate has never done such a thing! Support this, not that!"
Naturally, this doesn't account for those who say "
I am appalled at the actions of subject A! I was appalled when subject B did it, and was vocally opposed in equal measure, and I shall raise my opposition once again, especially as it is now the actions of one I oppose!"
Seriously, how often does that happen? People don't highlight a heinous action of their opponent after previously raising the issue and criticising someone they support. Why would you criticise you opponent for an action you abhore, yet STILL support your own advocate for having done the same thing and then using it as an argument to smear them?
It's more often than not done to use "moral outrage" to influence others. What's good for the goose is good for the gander, and if someone points out to you, by saying "
well what about when YOUR advocate did it...?" and you continue to argue that your choice is better in spite of it, it's hypocritical to continue to raise the issue if you're not prepared to denigrate your own candidate.
TL;DR, it's not about deflecting, it's questioning the motive and highlighting the hypocrisy to use the subject matter to demean your opponent and use that as a reason to inform others not to give that person/group your support... when you'd
(figuratively speaking) happily support your own candidate on the exact same criticism you've told others to not lend support to your opponent.
