The Trump Tower meeting was collusion between the Trump Campaign and Russia.
1. In response to your next question, the answer is "Collusion is not a legal term, so no, nobody was charged for collusion, and nobody will be because, again, collusion is not a legal term. What remains to be seen is which laws, if any, were broken in the process.
2. To answer to your response after that, the answer is "Yes, the trump tower meeting was collusion. If you say it isn't, then you need to look up the meaning of 'collusion.'"
3. To answer your next response, the answer is "I said the 'Trump Campaign,' not Trump himself."
4. To answer your inevitable statement that there was nothing wrong with the meeting, the answer is "If there was nothing wrong with the meeting, then you need to address why trump and everybody associated with the meeting lied about the meeting and tried to obscure its existence."
5. To answer your next claim, "Yes, the stories kept changing."

6. To answer your inevitable response that there was nothing wrong with getting damaging info on Clinton, the answer is "Then why did he and Donald Jr. claim for nearly a year that it was about adoptions?"
7. To answer your claim that it doesn't matter anyway because the Russians didn't deliver the damaging info on Clinton, the answer is "You don't know that."
8. To answer your claim that there were no crimes committed during collusion because nobody was charged, the answer is, "the Special Counsel's investigation isn't over." This will be the same response to any question concerning why there hasn't already been some specific outcome to the investigation you're thinking of.
9. To answer your claim that there's no evidence of a crime, the answer is, "The Special Counsel isn't keeping the public directly apprised of the status of his investigation, and therefore he isn't sharing that evidence with us. We will learn what the evidence is (if there is any) when the completed report is made public." This will be the same answer to any question concerning any development within the investigation.
Hope that helps.
