No. You've fundamentally misunderstood what the word 'bigotry' means. It happens a lot on this website.

Bigotry is the inability to listen to another person's point of view. That's it. That's all it means. Bigotry is evident by all races, both sexes and almost all political positions. It's not something which applies to 'the people who disagree with me'.

So no. Inviting people into debate and conversation cannot be a form of biogtry by definition. The only experimentation happening is that people have to step outside their ideological boxes if they want to engage. That may feel like cruelty, but discomfort is not the same as cruelty. And discussion and dissent is not the same as oppression.

I invite people to join in with informed debate and justify their positions. You do that. Anyone reading the back and forth between us can make better decisions about what they believe. That's how you challenge bigots. :o)
