Nearly every fruit tree you can plant in the US is "invasive." It really is not necessary to hate bradford pear trees quite as loudly as people do. We had an absolutely magical one in our front yard in Kansas- it was excellent in every way.
I don't go from place to place planting them, and I don't widely lament that they're on their way out, but you are subscribing to socially sanctioned hatred-as-sport in ranting and it's honestly fairly unreasonable. There are fewer and fewer of these trees every year; they are absolutely not coming to get you.
