There are definitely people advocating one-way trips to Mars. Buzz Aldrin wrote "Mission to Mars: My Vision for Space Exploration" (2013) pushing the idea of one-way trips and colonization by 2040. There are quite a few projects that have invested time and money into the idea. MarsOne (2012-2019) is possibly the most serious of the attempts, but they weren't exactly close to sending a mission.
