a few

[EUNJJUNG]

"Some students are so convinced of advocacy as the point of discussion that they see silence as the only way to avoid it:
"I wouldn't want to discuss religion as I don't want to impose my views on others."
A few explicitly generalized this model beyond the treatment of diversity issues, saying, 'Ideally, you should talk in order to make the other person realize that what they said was wrong," or, "I don't want to talk about things I'm unsure of.'"

What does 'A few" refer it?
and what does underlined phrase mean?
I can't understand that sentence.

What does "a few" refer [STRIKE]it[/STRIKE] to?
And what does the underlined phrase mean?

Note my corrections above. Note that a question mark ends a sentence; the next word has to be capitalized. Always use the same type of quotation mark to end a quote as you used to begin it.

The phrase refers to students.

I got it. I'll write a sentence carefully.
And what does the underlined phrase "beyond the treatment of diversity issues" mean?
I don't know what the word "beyond" means.

It means that what the writer is talking about is not restricted to diversity issues. For those students, it applies equally to all kinds of issues.
