If I ask you what time it is and you're not really sure, do you say "It's 1:04:35.023"?
So if you 'said it was a lab leak', but expected people to know you really mean "based on the extremely limited information I have on the situation, it don't feel the possibly of it being a lab leak can not be entirely discounted", then you've communicated poorly.
You've said in this comment that "you thought it likely it was a lab leak". Again, that's not the words of someone with low confidence in their theory.
Then we have to come to your motives in espousing such a theory. What was your point in saying that then and now? Is it that you think the world in general should work towards better lab practices? If so why not say that instead. Why do you want people to know you think it was from a particular lab?
Just saying what you're saying sounds a lot like an anti-China dog-whistle, especially in the environment in which you're saying it.
