Of course I accept Trump won in 2016! It's been certified. Trump is an incompetent moron, but he won the election.
Unlike Trump and MAGA fans, who cannot accept Trump lost the 2020 election and are making up ridiculous conspiracy theories, and are still claiming that Trump actually won the election.
You seem to confuse "accept" and "support". I'm not happy with every court decision or election result, but that's life! I have to accept them. It doesn't mean I support all of them.
