Bigotry is not a synonym for Racism. Bigotry is maintaining a personal opinion or prejudice even when holding that opinion or prejudice is unreasonable.

Can "Bigotry" include someones belief that a group of people are inferior because of their race, ethnicity, religion, or sexual preference ? Yes it can but it's so much broader than that.

Someone can also be a Bigot by holding the opinion that only Apple MacBooks should be allowed on Airplanes because they are the only ones with safe enough batteries and then refusing to change that opinion when presented with contrary evidence.

Bigotry isn't about people, it's about ideas, opinions, and prejudices all of which can be positive or negative on literally anything at all.

We have the "Paradox of Tolerance" because if we tolerate anything, including intolerance, then we have intolerance. If won't tolerate intolerance then we also have intolerance. It's that simple and it's also vastly over blown.

What we need to do is reject the unspoken implication that we must have a perfectly tolerant Society. Some amount of intolerance needs to exist but only so far as it has a positive outcome. Intolerance of racism is a good example, intolerance of non-defensive violence is another.
