Depends what you mean. Would not being the biggest club change who i support? No. Does being the biggest enhance my pride for my football club? Yes.
as an aside, my main annoyance with the scottish football community is that i really cant understand why people in Scotland find it so difficult to just support their own team and recognise the good that the supposedly evil fans and teams do. Why do they care so much about supposedly dead clubs that they spend thousands of hours on the internet, spending tens of thousands and being given tens of thousands by their readers, just to blog and post for the benefit of people who already believe their nonsense. Why can't, say, a Partick fan go out, support Partick and that be that? There always has to be some chip on their (any club's supporters) shoulder and a large degree of bitterness. The only explanation i can give is that because Rangers (and Celtic) have for so long been dominant, that these people now have it ingrained in them a degree of the wee man syndrome, as a result of living alongside a largely Rangers/Celtic supporting populace, which has led them to automatically hate and despise everything about the club(s) and find a negative in every single thing they do. Rather than maybe see things for what actually happened (a fraudster and criminal illegally acquiring a major business from which to siphon huge amounts of personal income at the expense of the taxpayer, then leading to the same club and fans being financially pillaged for three years thereafter by an assortment of crooks and dodgy folk), people who support these clubs prefer to blame that actual good guys. Although Dave King has been convicted of whatever, and whatever peoples opinions are on him or our fans in general, even the most ardent Celtic fans etc must see that these guys have Rangers best interests at heart, and any sane scottish football supporter would recognise that means they also (possibly indirectly) want to contribute to an improvement of the wider scottish game. Why not help and promote positive stories like Rangers fans groups now owning about 7% of the club, and have the biggest FO scheme in the UK.
In this backward wee country we prefer to slate that, criticise those same fans, yet somehow you all want something similar for your clubs, but just because its rangers (or Celtic), it must be a bad thing right?
Lets not get started on racism pal. If you want to go down that route i could find far more examples of racist behaviour from celtic fans (and staff) than from rangers fans. This seems to be another popular myth in scottish football fandom
