no, this is very wrong. there are LOTS of connecting words that can connect 2 complete sentences.
Whereas [complete sentence], [complete sentence][Complete sentence], whereas [complete sentence]Because [complete sentence], [complete sentence][Complete sentence], because [complete sentence]Even though [complete sentence], [complete sentence][Complete sentence], even though [complete sentence]Although [complete sentence], [complete sentence][Complete sentence], although [complete sentence]etc.
in fact, this is the ONLY thing "whereas" can do.
there is literally
nothing else that "whereas" can do, other than connect 2 complete sentences.
...so, i'm not sure where you got this "rule" from, but you can easily disprove it just by looking at basic examples of sentences using
whereas, although, etc.
