If you want to believe Venus doesn't show a closed loop with the Sun at the centre then be my guest, this type of astronomy is not for everyone.

I never made that claim, Gerald, I only reminded you that apparent planetary motion with respect to the Sun is not the only perspective. In your case, it seems to be the case that apparent planetary motion with respect to the fixed stars is not for you... but I can assure you that it is still astronomy.
