Yeah, well I don't need no uneducated old timer insulting me. Just because you are older than me doesn't mean that you are more intelligent, or better than me, and it definitely doesn't mean you can talk down to and deride me.
All that happened is someone pointed out that you moved a building that was an original building, rather than getting a version that is the reduced size that you were going for, AKA, it was inaccurate. Also, aren't the trolley shops a modern thing? When you go about saying that you are making something the most accurate way possible, then shift stuff around unprototypically so that you could have it like it was pre 1925, then keep stuff in that is more modern, you are asking for people to call you out on it. If you want to make a route based on a specific prototype, you make it based on the prototype, you don't pick and choose what parts you want then talk about how it is going to be extremely accurate.
Am I demanding that you change it? No, it is your route. I am just stating that you can't claim an accurate route in one breath, then talk about all of the things you are changing in another, then flip out like some spaz when someone calls you out on it. Heck, he wasn't even being rude about it. He was very polite, and just gave you constructive criticism. You flipped out like he was some kid straying too close to your overgrown yard and tacky pink flamingo decoration. (for the sake of argument, we will call him fluffy)
If you don't want people to provide you with historical information, tips, criticisms, and suggestions about how to make your "as accurate as possible" prototype route, then you should switch to freelancing, or at least stop claiming that you are making this the most accurate representation of the prototype ever. I am sorry if that is the way it is, but that is what the word "Accurate" means. Or at the very least, stop flipping out whenever someone lets you know that something that you are doing for your own personal reasons is incorrect. It would be like if I made the EBT, but decided that it was a 2 foot gauge, electrified line, but I told everyone that this is true to the prototype and yelled at anyone who told me that they use steam.
And finally, so a college undergrad is uneducated now? You obviously ain't got no fetchin' up.
tl:dr Stop being a crotchety old man and realize that when you throw around claims of total prototypical accuracy, then people are going to point things out that are wrong. They are trying to HELP you. Don't bite their head off. Just explain to them nicely that you are making the route the way you want to make it, and it might not be prototypically accurate, but it is the way you want to do it.
