Have you considered falling for appeal to emotions is not the best way to count score?
It's not that I'm validating emotional appeal but you have to be an idiot to not to anticipate it in politics.
Yes, emotional appeal is a fallacy. There, will that fix the overall perception of conservatives?
Anyways... There's plenty of evidence and authority appeal to suggest the separation of the children was wrong. I don't agree that a photo was used to strengthen the position but there were already opinions from medical professionals particularly pediatricians to suggest it was wrong.
Politics is not going to change because you want to be idealistic in this scenario. Neither will the media or organizational use of media like Russians buying Facebook ads. They weren't buying ads to promote businesses...
Again, that is today's world and all political leaders have to deal with it.
What could possibly make this hypocritical for anyone is to highlight it when it's done against one's agenda but turn a blind eye when done against the opposition.
