They're using an increasingly popular derailment technique called the common ground fallacy.

The parent is asserting that the truth is merely a compromise between two different opinions, when in reality there's evidence enough to assert the truth, without making it a matter of 'right' or 'left' opinion. Their inability to provide their credible sources ("high def video") is because their opinion doesn't align with the reality of the situation.

Of course I rotated it. And my point stands. The perspective is still different. The rows of people are countable, and looking at some of the further sections there is no way I would be able to count as many rows as at the other. There are 2 sections filled with people at the Obama one that are completely blocked off on the Trump one. That can't be argued with at all.

There are people who are good at estimating crowd sizes and I'll let them do their job. But, once again, this picture in no way contradicts the others.
