No, no, no, no, no, no, no.

ALL Web traffic should be https (or http/2 or /3). If you connect to a site that uses insecure http, ANY link between you and that site can easily snoop on traffic and even inject different content. You CANNOT be sure that the content you see is what was originally served by the server, and you can certainly expect that state actors will be noting that you viewed this content, and building a profile on you based on that information.
