I found that video via "Lincoln Project Gets Personal In New Ad, Mocking ‘Impotus Americanus’ Trump’s Weight and ‘Ruddy Orange’ Color" (Mediaite). Excerpt:
In an online town hall with supporters Thursday night, Lincoln Project co-founder Rick Wilson discussed the philosophy behind ads like this.So, they are choosing to bully him, and they don't mind collateral damage to the many Americans who are fat, who have light pigmentation, and who worry about the vigor of their masculinity. The Lincoln Project doesn't do it "just for fun or to amuse ourselves" — but the "just" implies that they are enjoying themselves taunting Trump. So here's a picture of Rick Wilson. He has liberated you to say anything you want to roast him based on his appearance:
“When you see the ads talking about Trump’s personal weaknesses, physical, mental, what have you, those are targeting one voter: Donald Trump,” said Wilson. “Now, we don’t troll Trump just for fun or to amuse ourselves — God knows, that would be a great job all day, ok? Trolling him would be a fabulous job, but we don’t do it just to troll him.”
“We do it,” Wilson continued, “because every second Trump is distracted by a Lincoln Project ad, that is playing with his psychological weaknesses, that is playing with his mental frailties, that is playing with his weird ego problems — every moment he’s focused on us, he’s not campaigning against Joe Biden.”

ADDED: Quite aside from the collateral bullying of men who have the same physical deficiencies as those that are attributed to Trump, many women — including me — don't like to hear judgment of men that is based on their ability to have sexual intercourse with women. We're sympathetic to men who have problems finding a woman or performing sexually, and we think publicly mocking them is jackassery. And I know Trump speaks crudely and tauntingly at times, but if you do the same thing, you sacrifice your power to criticize him on that ground.
