Alex, there is no meat in your advice. With hundreds of thousands of writers, how can one find those let us say, a dozen who are interested in taking on my challenge?

In particular, I did my homework on the immigration issue and formed strong opinions. I want to challenge other writers to write polemics. I would like to see other ideas. I see the value in having a deep candid conversation about our immigration policy. I opened a publication on Medium dedicated to political debates, https://virtualagora.us/. How can I find o Medium authors who want to prove me wrong? Or want to prove wrong anyone else, a politician or a pundit. How can I find writers who are not involved in political writing but might have personal experiences or observations that can enrich our conversation?

What are the tools at Medium that allow me to reach other writers? Or encourage the readers to do the same?
