Yeah, it's a Righty one.
The only Liberal meme I ever seen to hit #1 was round 2018 (maybe 2017). It was about a plastic straw being removed from a sea turtle's nostril. That's it. The only one.
Until some point in 2017, it was just the Main stream, so it had a mixture of themes. But then it was split into the Fun stream and the Politics stream because the Trumper inundation was chasing everybody else out. It was too late, as the the Golden Era of imgflip (when there was a lot of activity, growth, creativity, community) was already fizzling by that point.
I myself only had two to hit the top spot, one was a repost about feminazis in 2016, the other was with a different account, and it was an ambiguous take on the trend of taking down Confederate statues, focusing on garden gnomes.
Best meme I ever made!
Scared me though, because waking up to a ton of notifications, and replying to 1 only to find this 5 more to follow can be a tad distressing. I spend an inordinate amount of time searching for the right pic, and trying to come up with a halfway decent caption, so the notifications all keep piling up while I keep falling farther behind.
