It depends on what you think a supporter is. The club is and always was a commercial business unless you give it your money you are not helping it and hence by definition not supporting it. If no body paid the club would cease to exist.
I don't see how anyone could see it otherwise. But it's also more than money ad viewing angle I have been to many games with Liverpool and is about the travel the drinking in pubs before the flags the being part of a huge swell of people all i
With the same aim.
If you have never witness that then sorry but you really cannot say you are a supporter. Sorry it that sounds harsh. But watching on the tv is not or ever will be anything like attending a real game especially a final or something like that.
I agree that people not attending miss out on a large part of the atmosphere/occassion but you CANNOT say that they aren't proper fans. Supporting the club, how you do it and what you get from it, is subjective.
The club relies so much on support/finance/players/staff from further afield than the immediate vicinty of Liverpool........so whilst you think you're a great supporter I think that the club would be disappointed in your attitude.
