Glancing at it I feel that you don't need numbers fam. The ancaps there seem like total midwits, the classic pretentious middle-class dudes in their late teens/early 20s who will run away as soon as they feel threatened by the level of the debate, because they're not very smart and their egos won't allow them to face that.
So what you need is resources. You need to learn to deconstruct ancap politics and attack it at its foundations, you need to bring up historical record of capitalist governments doing evil shit, you need to learn some basics of Soviet apologia (as hurtful as this will be to you), you need to learn about the millions of ways the State has and still does help sustain capitalism, you need to bring up dumb and nasty shit that libertarian institutions have defended, etc. And you need images, memes are nothing but shit we're tired of repeating and rewriting every single time. Follow two lines: 1. Shift the debate to your terms, bring up your arguments and shit, instead of letting them frame it and put yourself in a defensive position. 2. Learn to make it too much of a hassle for them to maintain a presence there. It takes no energy to go "lol Venezuela", it takes a lot of energy to respond to more complex arguments and do apologia for capitalist governments, particularly if they were previously unaware of its actions.

I'm also 100% sure that one of the historians who popularized the Ukrainian genocide wrote in the preface of one of his books that the damage was clearly not intentional. Look into that.
Also it's no hard to frame that (and many other so-called Soviet atrocities) in terms of consequence of capitalist policies. Stalin was on the side of Bukharin for most of the 20s, and the policies they defended (and led directly to hunger) was one of allowing petty bourgeois property and market relations in the countryside. Sanchez-Sibony's Red Globalization is an academic work that explores the consequences of global capitalism on the Soviet course of action.
And of course, if you learn enough about imperialism, you can just What About the shit out of it.
Sorry I can't be there with you, I just don't have for this shit and I don't want to re-activate Facebook. If you want to gather numbers, join Left-wing facebook pages and Discords, and link to your debates there. If people see you there debating them, and debating them well, they will gain the confidence to join you.
