How many are "too many"?

[D1042 Western Princess]

I'm not sure Greg (aka D1042 Western Princess) will be too pleased with being called a "she" either! 

There may be more than one of us- I mean you lot who are guilt of making that mistake. But what can you expect when a bloke calls himself a princess! 

The question was how many are too many? Basically, how many locos over the number needed to run the layout do you think you should have before saying "enough"? Why do some seem to think the question was about shoes??
Why do others seem to think a person choosing the name of their favourite loco (for VERY personal reasons to do with my lovely girlfriend) are good reasons for personal insults?
Really I think this thread has run its course and think there is little point in continuing it.
I genuinely thought it to be a friendly site, but some comments are making me wonder.

[Tank]

I don't think anyone meant to insult you, they just saw your username in a different context.

I'm locking this thread now.
