Not necessarily.
For example, recommending videos that are somehow categorized "pro-evolutionary theory" would almost certainly be less divisive than recommending Creationist videos that attempt to "debunk" evolutionary theory. The pro-evolutionary theory videos would typically be substantive scientific talks or lectures that require patience and critical thinking in order to understand. The Creationist videos, on the other hand, typically use lots of underhanded tactics. They will attempt to mislead the viewer and typically throw out so many different arguments from so many disparate fields that it's impossible for any one person to debunk them all out of hand.
If you recommend the "pro-evolution" videos you probably end up with a lot of bored viewers who don't even make it through a single video. If you recommend the "anti-evolution" videos then you'll get a biologist debunking point 1 of 100 and a troglodyte responding "what about point 2-100?"
I have no clue whether the pro/anti Brexit videos fit that bill. But it's certainly a possibility.
