I have no problem with owning lots of bikes either. There are 7 in our garage.
I do have a problem with equating the shifting of gears, "appropriate cycling gear", cadence, "undulation", "non-roadworthy bike" or whatever other measurement that might be written about profusely in a bicycling magazine with "skilled" or "serious". As if the multitudes undulating and mashing their non-roadworthy bikes while wearing street clothes were somehow un-skilled and not serious about the business of getting to wherever they are going.
