No need to apologize, precision is important. Perhaps my point blurred two different things.
Point number 1 (directly referencing your question):
No, I did mean it's easier to heat than to cool. Basically every mechanism release heat, including heat pumps. Ultimately, to get a person to a comfortable temperature, all that is needed is to wrap them up in insulation until their body heat matches the heat loss for the required Delta(T).
Cooling is another thing altogether. There is no cooling mechanism, all we can do is:
Your body can do 1. but only if the humidity is low enough, but it can't do 2. My conclusion here is to illustrate that your body can largely take care of itself when it comes to warming itself up, but it's (comparatively) very bad at cooling itself.
Point number 2:
While heating is very easy, it's also very energetically wasteful for two reasons:
1. The Delta(T) you have to fight against is larger, often double so the losses are larger (Delta(T) sets the heat loss of your home)
2. Most heating isn't done with heat pumps which are very efficient, whereas all cooling is pretty much only done with heat pumps [1].
3. You can use heat that the AC moved around. Today you can hook up your AC to your boiler so the heat you moved out of your home is dumped into your boiler. As long as you use enough hot water, the more you run your AC the lower your carbon emissions will be since the water boiler runs off gas (I'm not advocating for using more hot water, btw)
So, while using your AC is not good for the climate, it is not the easiest optimization to do first.
[1] Swamp coolers are weird: you live in an arid enough place that evaporating water cools you down... so you waste that precious water when you could just run an AC???

Cooling is another thing altogether. There is no cooling mechanism, all we can do is:
1. absorb heat (i.e. evaporation) 2. move it somewhere else (i.e. heat pumps)
