Cytat:
Who has ever developed more than one theory of relativity of something or other?
This is irrelevant. The sentence talks only about Einstein.
Cytat:
only prototypical sentence subjects are normally agents and topics at the same time. "Only Haydn… "and "Even Haydn…", for example, are explicitly not prototypical and the sentences they head do not have to be about the subjects (and are not, more often than not.)
"Only" is just an adjective here. It gives some more information about the pronoun "Haydn" but doesn't magically make "Haydn" anything other than the subject and the topic of the sentence.
Cytat:
You are a fool, as I said before.
You've said it many times already, and not only about me, and not only under this account. That's just your way of raising your ego made easier by the anonimity the Internet provides.

One more time I please ask everybody to write in Polish, especially it refers to the user Janski. .
Pisanie po angielsku legitymizuje Janskiego. Gdyby pisał po polsku, to brzmiałby bardziej "swojsko" i przez to nikt by na niego nie zwracał uwagi.
Natomiast mam nadzieję, że pokazałem, że to, że ktoś pisze po angielsku, nie znaczy, że wszystko, co pisze jest mądre.
