@wildcolonialboyI have read about Clause 28 in the 90s and visited people there in GB and have spoken to them. They lived in those times. The 90s were still the time of the AIDS catastrophe. But yes, wikipedia knows better always, I know.
I did read through your comment too quckly and thought you mentioned Jimmy Saville not Somerville (hence thinking you were linking homosexuality to child molestation etc)
On the other hand, it's still not entirely clear what you're getting at re Section 28. The actual legal reach of the act was strictly limited to local authorities (directly quoting here, nothing to do with wikipedia)
(1)A local authority shall not—
(a)intentionally promote homosexuality or publish material with the intention of promoting homosexuality;
(b)promote the teaching in any maintained school of the acceptability of homosexuality as a pretended family relationship.
In its limitation to local authorities (i.e. local government, and by extension schools) it didn't have any influence over television or the arts. In the late 80s and 1990s there were quite a few depictions of homosexuality on TV and in film.
