Hi! How is it going? Thanks in advance!
E.X. You are victims too.
1.- Can I drop the verb "to be" and use the sentence this way to
mean they are victims (in a figurative sense) as well?
E.X. You! Victims too!.
2.- I am not sure of the adverb too. Is it used correctly here?
Have a wonderful day!
Only in spoken or casually written context. Too is appropriate. Your exclamation marks are beside the point, and carry information not in the original statement.
