And if you think that embracing that logo enhances said person's level of support, then logically we have a bunch of people who stopped supporting the university when they voted to allow the nickname to retire. If the same wasn't true then, logically it shouldn't be true now.
If allowing a nickname to pass was supporting the university, then embracing a new nickname to support the university is changing the rules. If the stance when taking the nickname down was "allegiance to the school, not the logo", you should more than allowed (it was previously encouraged, correctly) to hold that same stance now.
