There is no possible way the Raka and Cait can win without doing some next level outplays or simply having the jungler intervene.
Funny, I never found this to be that hard. Just avoid their skillshots. You get to play from a very safe range and sustain > poke. If you're losing this lane, it's because you aren't playing it correctly.
As for the video, it's foolish to take it too seriously, because his argument boils down to "People don't like supports because they don't stroke your epeen hard enough." The one point he casually mentions as an off-handed comment is the real reason: You're stuck in lane with a crybaby, entitled ADC who thinks he's a lot better than he actually is.
If he were as good as he thought, he wouldn't need a support, nor rage when the support goes to gank another lane. He would know how to avoid poke and CC, he'd put down his own wards in conjunction with yours to make the lane safer, he'd know when/how to fight under tower and when to leave it, he wouldn't miss 50% of his CS.
This is why I always tell both supports and ADCs that they need to learn how to evaluate how good their lane partner is, and play accordingly. As much as it sounds like I'm bashing on ADCs here, the reciprocal is true too: People don't like to play ADC because of undependable support players. But that doesn't get talked about in that context--it's always instead phrased as "ADCs are bad this season," or "How to fix ADCs." People always forget that lane is a 2v2 by default, so talking about one without the other is a bit like trying to talk about politics without addressing economics (or visa versa).
