1. Gain of function research primarily uses samples collected from nature, and seeks to stimulate their evolution in as natural a way as possible to learn how viruses evolve in nature. If such viruses were to escape the lab, they would appear "natural"
2. It's not xenophobic for people from the US to suggest the possibility of a lab leak, because the US was itself funding gain of function research on novel coronaviruses in the Wuhan BSL4 lab
3. Lab leaks happen more often than most people realize[1]

Inherently? Of course not. But does xenophobia motivate a lot of this argument? It certainly seems to. Look at how quickly proponents of this nonsense jump from detached discussion about the possibilities to outraged condemnation of the PRC. Just read the discussion here in this thread.
If you only wanted to discuss the lab and the virus and try to put relative likelihoods on the natural evolution vs. Andromeda Strain theories, that would be one thing. But... that doesn't seem to be all you want.
All we need to do to take xenophobia out of this discussion is to not be xenophobic ourselves. The xenophobes may talk to themselves. But let's make sure we are talking about this problem instead of falling for the "guilty by association fallacy".
