I very recently met with a YouTuber who I admired and who I'd been following for a few months. I learned what they say is true, "Never meet your heroes."
That wouldn't be a problem for someone who is able to look at heroes, family, people they love objectively and not idealize them but allow them to be full human beings with quirks, bad habits and even big flaws. Sadly way too many people tend to build idealized images of others,
no matter how they meet or know them, in their minds and often feel 'betrayed when some event or conversation forces them to view the person as a whole human being. This why people 'looking for love' should give some thought to what beliefs, traits, habits of the other would be 'deal-breakers' for them. And then spend some time getting to know the person in various situations. Online you can't observe how someone talks to 'service people', but you can see how they talk about people, and how they talk to people they've had conflicts with; sometimes with arrogant people you can even tell who they feel is 'beneath' them and so not deserving of common courtesy and respect. (Not surprisingly these can be folks who espouse humanistic attitudes, and whose opinions may err more on the side of being 'PC' than being honest.

Example of viewing someone well-loved objectively:
As some may have guessed by some of the things i've said, i adored my father as a child and 26 years after his death i still cherish him. The foundation he gave me in life was invaluable, i would likely not be the person i am or even alive this long if not for his teachings, nor would my children have turned out as well they did because i raised them as he raised me that first decade when i had him in my life (he was absent from the 2nd time Mom left him till i went looking for him at age 19 and was never very good at Long Distance interactions except the letters he sent that convinced Mom to give him a second chance).
That does not mean, however, that i couldn't/don't see his flaws: He was a better father than husband (as one might guess from the 5 marriages), he was a womanizer who always had to have a 'spare', a woman on the side until some point during his last marriage. He learned quickly and most people assumed he was college educated but if he couldn't master something quickly he'd put it aside and pretend he'd never attempted to acquire the skill rather than admit 'failure'. (Found that out from his Best Friend whom i met when my then #3 DH, daughter and self were caring for Dad when he became terminally ill.) He was verbally abusive with his first two wives for sure, and occasionally physically violent with them but they both were volatile, threw things and got violent too. (Doesn't excuse him, but doesn't make them quite full on victims except maybe of the generational conditioning to the idea of having to put up with it.)
