I agree wholeheartedly with what you are saying; when you expand on what you mean past just ‘there are too many people’ and actually suggest realistic meaningful solutions like you have here, I highly doubt that most people would ‘accuse you of all sorts of things’. It’s just that when you simply post ‘there are too many people’ this implies there should be less people, to most people they would interpret that to mean in an immediate sense, aka unaliving them.

Now that you’ve expanded on what you had to say I can see that clearly isn’t what your intention was to convey. I would just like to say though that considering human population level is not a factor we can control without death or reducing birthrate, and birthrates are already reducing globally, you should be able to see why many would assume you are advocating for the other option.
