The problem is that it's not really a loaded question, but a valid response to the idea of an age cap amidst indefinite life spans. How do you propose capping the life span of an adult without the use of a termination agent?

I am not proposing anything. I don't know how we can cap the lifespan of an adult. But I do know that if we have a cure for aging today, i.e. people stop dying from this day onwards, the population is only going to keep growing and that doesn't seem very sustainable. This is, of course, given that people continue to have children. Halting the production of new offspring could be interesting to witness from an evolutionary standpoint.

As far as the loaded question is concerned, I did sense an inflammatory tone in kobeya's response with the gas chambers question. Your response, on the other hand, is more discussion-oriented and open-minded.

Except it's not a loaded question at all -- administrative murder seems to be exactly what you are proposing.
