Wa aalikum salam

Spending time in something which is not prohibited is permissible as long as duties are fulfilled and no haram is committed. As for going to museums, here is a link: https://www.assimalhakeem.net/node/5807

Assalamu alaykum, If there is a science Museum with permissible exhibits but aslo Kufr ones and you have to pay enter the museum as a whole, if you visit the permisibble ones and leave the Kufr ones, is this classified asapproving of Kufr because I only want to watch the permissible exhibitsand hate the Kufr ones and I have no intent to support the Kufr but when you pay, it is as if you approve?
