wait a minute. you're a guy and you ride a women's bike?

Oh, really? Here's your entire post from the above referenced thread:
"I mostly ride on the sidewalks. which is easier to do on a folding bike with smaller wheels. mine is a 20 inch. I find its easier to maneuver on the more confined space of the sidewalk than a full size road bike. the roads are far too dangerous for cycling imo. drivers are often unpredictable and you are hard to see on your bicycle. at least on a noisy motorcycle you have the advantage of being heard because everyone can hear you coming from a mile away. but of course the bicycle offers no such advantage. you are completely silent. so in that regard the bicyclist is much worse off than the motorbike riders at least when riding in the street."

The subject of top tubes and standing at a stop were brought up in this thread by you.

The fact is, a proper sized frame- regardless of TT design- isn't going to harm you when you come to a controlled stop. All bets are off when it comes to an uncontrolled stop, though...

^^ Not that there's anything wrong with that!

again, where did I say anything at all about stopping, top tubes, or flat feet in that post? your imagination is running wild. that post was about maneuvering on a folding bike, not stopping.

do you know the difference between maneuvering and stopping?

Maybe you should state what bike(s) you are riding to clear up any future (perceived) misconceptions?

The top tube and placement of feet while stopped was brought up in this thread.

I know my limits when it comes to handling a bicycle- stopped or in motion- and been riding for more than 3 decades.

Yes. I've had three ladies' bikes. Technically one mixte and two ladies bikes.

You should try one out. It's like sloping top tube turned up to 11.

Horizontal top tubes are more comfortable to lean against if you are feeling lazy.
They are easier to shoulder (cyclo-cross style) and carry the bike.
On smaller sizes, a horizontal top tube places the seat cluster and the rack mounts higher than for sloping tubes. This means that rack stays can be in-line with the rack top, maintaining triangulation and stiffness.
Horizontal TT provides clearance so your dynamo front lamp (on the fork crown) does not intersect with the top tube if your bars flip. I have cracked expensive lamps on my sloping TT.

Sloping top tubes are more about bike manufacturers reducing the number of sizes they have to make than protecting riders personal property. By sloping the top tube a greater number of riders can use a given size than is possible with a relatively flat top tube.
