Combining two sentences when they share same group, but the one is subject and the other is object.

First of all , I was building a sentence.

The statements of protesters were condescending to almost everyone of whom were not present.

I didn't want to use a noun after 'everyone of.' And 'whom' was put there just because I think I saw someone using it that way, and I thought probably the noun that is followed by 'whom' could be understood in this case.

But at this point, I have no idea what I was doing, so changed a part of the structure to stick to what I know is grammatical.

The statements of protesters were condescending to almost everyone of (those, the people, or them) who were not present.

Now it seems too repetitive.

Also, the relative pronoun 'who' seems misplaced since it follows the object of preposition.

It seemed to me that 'whom' should take place of 'who.'

Or entire things after 'who'

To simplify, I made two sentences.

"The statements were ~ to them." or "The statements were ~ to one of them."

"They were not present."

But, was that even possible to combine these two ? When the one is the object and the other one is the subject?

And if it is not possible to do that and first sentence is impossible too, what sentence structure would be better to clarify the meaning ?
