Leftism is a religion, and a fanatical one as that.

That is why they have to insert leftism into places where politics never existed before, whether it be :
1) The Miss USA contest
2) Schools
3) Ads for products that the producers presumably want to sell as many as possible of

The right is very weak against the left. This is because conservatives have jobs, friends, and families, while leftists have none of these things. Leftists, if they have jobs, are in jobs that promote leftism. Thus, a leftist can spend 100% of their time on politics, while a conservative can spend 5%.

Thus, 1 leftist offsets 20 conservatives, in terms of propaganda effort. That is why the left is so powerful, despite the majority of people being center-right.
