I find very often that those who make the biggest issues on blogs about chumros are the kulah shoppers. They can always find someone who is meikil in a certain issue and thus the machmir or anyone who follows the chumrah is wrong. And this attitude is at least as bad as someone who keeps a chumrah looking down on someone who does not and probably worse since they often will end up being oiver on the halacha. And those kulah shoppers (I am referring to the extreme ones, those who constantly scream about kulahs on the blogs) tend to look for any kulah, even when using a kulah in one instance would be completely contradictory to a kulah they used in another instance. They tend not to have any consistency to their approach to halacha other than if there is some kulah, we will be meikil.
And of course, what determines the greatness of a rov for these kulah shoppers is if the rov is meikil. Denying the truth that very often it takes even greater strength of will to be machmir.
Yes, if you follow a rov (at least if he is not a mechadesh devarim sheloh kehalacho, such as some well known radicals nowadays) and use his kulahs it is appropriate, if you also are machmir when he says it is appropriate. But if all you do is go from meikil to meikil and are not consistent, then it highly unlikely that you are doing anything appropriate.
This is without discussing the “innovators” who do not rely on mesorah at all, their basis for halachic decisions are “feelings” or being politically correct or to try to fit in with the corrupt popular culture.
