My chief complaint is these people w/huge strollers (double or single) as some of the single strollers can be just as big. When my kids were 1 and 3, I brought an umbrella (with an extended handle, as my husband is 6'3) and a smaller single with an under carraige to carry some things. I think some people can really relate to these people who have these huge strollers and think they rule the walkways. Not only in the park, but in the elevators, on the streets, etc. I just think it's rude. We were at Seaworld and Legoland a few months ago and you could barely get around some places at Seaworld. Legoland is much more open so that was easier. I do realize there are rude adults that stand in the way, etc, I just feel like these people with ginormous strollers think that because they have kids in them, they have the right away. I know my opinion is not popular, but I think some will agree that it's true.
I've read your posts over and over and you still have yet to answer the basic questions other people have posted, which might be summed up as, "What exactly, specifically, in easy definitions, is the behavior that irks you? What should I be doing or avoid doing?" Because you have not said anything that says to me that I can in any way have a double stroller without it pissing you off unless I somehow manage to never be in your way and/or just submit to your definition of "respectful," which is bring a tiny stroller like you do, neither of which seem a reasonable request of others in a busy public space. The people who seem so rude to you here, that they don't care about others, are actually saying, "Wow, there is just NO WAY to please you, so I really just need to do what is best for my family and be as courteous as I can, but I guess there is just no pleasing everyone. Especially people like you, where there is only one correct way to be in the parks, which is your way."
If you can't spell out what specific behavior(s) is so bothersome (other than your perceptions about people's attitudes) once people explain that they need a particular stroller to suit their needs--a stroller different from the ones that satisfy your needs--people feel that they cannot find a reasonable way to accommodate you.
ETA: I would like to point out that in the course of this thread, prospective visiting parents have been told, among other things, that:
1) Anything bigger than an umbrella stroller is going to irk a variety of people.
2) Some people have 3yos (feel free to insert any other age you like) who can walk and stand all day in the park, so they are going to assume that yours should, too, as if all children are the same--or if the kids are not all the same, they will think it must be because you are doing something wrong.
3) If you try to use an alternative like the popular leashes/leash backpacks, that will just irk someone else.
4) You can't go shopping with your stroller, beause if there are tight spaces, you personally will be blamed for bringing the stroller rather than the poor shop design, even though my understanding is any place that is not wide enough for an average double stroller is not wide enough for an adult's wheelchair, which they should be by law. But using the stroller, unlike the wheelchair, is seen as being purely a choice, and a selfish one at that.
So let me be one who wants to thank all of you who are bringing strollers, no matter how large.
Thank you for bringing along a stroller that will carry the things that will help keep your children calm and happy while in the parks.
Thank you for bringing a stroller because you have a child like my 4yo, who would not make it through the day without some combination of lagging far behind the family or whining about how tired he is from the walking and how he needs a stroller or to be carried.
Thank you for bringing a stroller because you have a child like my whirling-dervish 2yo and you are doing your best to contain them when moving from one place to another or at a stationary event like a parade or WOC.
Thank you for trying to do the best for your family, because as a parent of a special-needs child with an "invisible" disability like my 7yo, I know how it is for you have to do things differently from others and feel people judging you for not conforming to their standards.
Thank you for bringing a stroller so you don't strain your back when a tired or sleepy child needs to be carried, because I want you to have a nice time, too. And being around other people who are having a more orderly, nicer time allows me to have a nicer time. So thank you.
