It's also easier to find those we disagree with if you are curious. It's also harder for the incurious to suppress such curiosity. If you have never found and explored deep wells of previously alien thought online, then I doubt you would have been so interested in meatspace either.
The fact that effort is required to find those we disagree with (on the internet) demonstrates the weakness of the internet to meatspace. Merely showing up for work will expose you to those who hold viewpoints with which you disagree and unlike an anonymous internet belief-holder it is much harder to dismiss or entirely define a person purely due to that belief when you are around them for several hours a day. We may disagree with each other deeply about politics but share a love of pho and eat lunch together among a myriad of other commonly shared experiences. It makes it much harder to think of people as caricatures.
