If you aren't saying that he should, then why do you keep bringing it up and addressing him as if you believe he should. You have pressured him to renounce the BNP multiple times now.
Had you mentioned it once and let the matter drop, I might be inclined to believe your current claim that it was only a matter of interest. But you did not do that. Instead you kept pressing, which is a sign that you are not being truthful about your current intentions in raising the point.
What pressure have I exerted? I asked him a question and have commented that he refuses to provide an answer.

I am not pressing him. This is a discussion between you and me. If he chooses not to respond, that is his right.
Show me the "multiple times" I "pressured him" then.
