(S)he is probably touching the problem when all parties that are supposed to be normal would vote for this extreme legislation, and only extremist ones would oppose it; i.e. the problem will be the lack of choice in that matter, caused by parties themselves; a situation similar leading to the election of current US president where many people just voted "in jest" due to not being heard and not having any means to voice their concerns. I am frankly not sure how to address this beside starting an own party and gaining required % support to get into parliament.
