Mike Wallace needs to learn how to RESPECT gay people ... so says the Miami Dolphins organization, which says it strongly condemns the comments made by their star receiver.

A rep for the NFL team tells TMZ ... the Dolphins took immediate action once they learned about Wallace's homophobic tweet, in which he condescendingly questions why Collins would want to "mess with other guys" when there are so many beautiful girls in the world.

The Dolphins tell us ..."Mike Wallace has apologized for his comments, and we have addressed the matter with him."

"Mike’s comments do not reflect the views of the Miami Dolphins. We believe in a culture of inclusiveness and respect, and any statements to the contrary are in no way acceptable to our organization."

"We will address the entire team about our policy of inclusion and make sure they all understand the importance of respecting individual choices.”

Wallace has since deleted the tweet.
