There are two primary reasons nobody is willing to debate you, which are that your particular brand of antizionism is so rigid and dogmatic that there is nothing to be gained from talking to you, and because your ideas and opinions are irrelevant to the future of Israel/Palestine. You operate in a self contained bubble of likeminded individuals who feel that your cause is not only just, but any deviation from your preferred narrative is inherently immoral.
More importantly, your views and opinions have no impact on the future of Israel and Palestine. There is no broader audience for your advocated one state solution, because any student of history understands that forcing warring ethnic groups into a single national body only ends in bloodshed. The idea that sufficient international pressure (and this is assuming you are capable of producing such pressure) could convince either Israelis or Palestinians to simply abandon their national aspirations is childish naiveté.
Palestinians have resisted military occupation for the last nearly half century, as well as mass displacement, and have not abandoned their national aspirations. Jews have existed in a state of diaspora for thousands of years without abandoning national aspirations, and have now seen them fulfilled. Why would either group decide willingly to abandon such clearly strongly held senses of peoplehood, and for that matter, why should anyone be forced to do so?
