A large amount of people disagree, but what has come out after the vote has shown than an even larger segment voted because they were intentionally lied to and confused about the actual contents of the agreements.

It was actually pretty funny, because the leader of the NO campaign gave an interview boasting about how they had successfully conned the country into thinking that gender ideology gay marriage and other subjects were being voted for with the agreements (they estimated that over 2mm evangelical christians voted No because of this), and how by lying on social media they managed to execute an incredibly cheap political campaign. He was removed as campaign leader the next day and the opposition quickly distanced themselves from him by pretending his role was minor, since he is also pending penal investigation and will probably go to jail, since under Colombian law intentionally lying to the electorate to change the outcome of an election is punishable by law.

This was the actual interview: http://www.larepublica.co/el-no-ha-sido-la-campa%C3%B1a-m%C3...
