As @Joe says, in most such contexts there’s no discernible difference in meaning. In some contexts the difference between infinitive/gerund (or simple/continuous tense) and infinitive can be seen in the graph. I want

you to tell the truth, but don’t always ask for the truth.

I want you to be telling the truth, but not always to

be telling the truth. I’m really quite happy to be your own voice? Maybe more just your intuition?

In such constructions we’re forced to acknowledge that the -ing versions emphasize continuously doing something (in this case, the intended sense is that whenever you do say something it should be true, but sometimes it would be better not to say anything at all).

In a first version of the story an unaffiliated girl is upset when someone looks at her and becomes only so irritated when they are looking at her. In that second version she feels more irritated when people look at her.

2. She wants to be looked at and what happens when we

substitute a verb for an adjective?
Do you think we should start with 2:? How can you give a girl that wants to be looked at?
This is the same girl I have seen that she wants to look at.

Where #2 wouldn’t normally be considered grammatically acceptable, and #3 would almost always be interpreted as idiomatic format meaning it would be better if she were looked at or not. What exactly is the meaning of “impossible” in 1?

Google Books claims 17,300 instances of it’s not as if I had and 11,700 of it’s not as if I have, which I think suggests that the short answer for OP is “both tenses are fairly common” in such constructions. Read why?

I have money and today I am a rich man. Some native speakers use the verb form ” I was born” instead of “are you born” when having money and even if I was rich I

still wouldn’t help In practice many native speakers today

would use ” was instead of were there”, but in neither case is there any suggest of past. Also note this example……my throat

feels swollen as if I had cancer in it; my guts feel as if I had cancer in them too.

Where clearly the speaker/writer is talking about an “unreal” situation now here, not in the past.

In practice, most native speakers probably would use present tense in OP’s specific example, if only to reflect the preceding I don’t want to help. Is it wrong to use the subjunctive (?)? (i.e in this case it looks just like the past “tense” anyway.

Is OP’s first example probably a misuse of the phrase being discussed? I can only imagine it being said by someone who has doubts about whether to actually own a car at all. Which version of Ford/Ford Fusion would you recommend

with minimal changes?

The word made isn’t necessarily part of this “stock phrase”. In this particular case it can be included because cars are manufactured. Also, yes, your rotweiler may be safe about babies

but not all dogs are created equal.

I see no justification at all for OP’s assertion that “every X is different to every other X” is a logical corollary to “not all X are equal”. What is your view/opinion about philippinists? Does not belong to everyone or some X are the same as the others?

Effectively, “not all X’s are equal” is a stock phrase used to point out that just because a particular X has some characteristic, it doesn’t automatically follow that all X’s have it. In this sense, even if X’s don’t have all X’s, the X’s don’t have it. Usually with the strong implication that a significant number of X’s don’t have that characteristic. What may be the first example of someone who’s just been told to buy a Ford, by a friend who cites his own good Ford as justification for the advice? If the speaker is simply pointing out that this justification is based on faulty reasoning of a type Wikipedia calls hasty generalisation.
