Let me try to explain the issue (and maybe discover whether you are 
an -ist of some kind).
Imagine an ordinary physical object of some everyday kind, such as a 
table. Let me put down a few simple facts and see if you find them 
reasonable.

The table lasts for a time, and is the same table at one time as another.
The table has properties (such as a length, a weight, being made of 
pine, and being in the kitchen). Some of these properties may change 
as time passes, ie the table has these properties at one time but not 
at another time.

These seem reasonable, I expect. However, they are not ontologically 
neutral. They are couched in endurantist language. A 4-d ontology 
would not say that properties changed: rather, it would attribute 
properties to the temporal 'episodes' (slices) of the table. These 
properties never 'change'; in fact, such talk is meaningless in a 4-d 
ontology.  And in this ontology, the idea that it is the same table 
at one time as another is provably false, since one thing cannot both 
have and not have the same property; rather, there is a single 
table-history (sometimes called 'worm') and the properties in 
question are properties of slices of this history.  The sharp 
distinction between things that endure and processes that happen is 
much vaguer in this framework: it can be made, but only artificially, 
and it plays no fundamental role; whereas in the endurantist view it 
is absolutely central.

My dear fellow, you have no idea how polarised people are about this, 
and have been for years. Entire libraries have been written arguing 
one or another position in this debate; rather strong language has 
been employed (philosophers who speak of a different position as 
'evidently unsatisfactory' or 'clearly unintuitive' are close to 
armed combat). The terms arise from the world-views; they are not 
mere labels being used to foment political ambitions or create 
childish quarrels.

There are good reasons for both the endurantist and perduarnatist 
points of view; they are not just party labels. Endurantism is 
reflected both in natural language and in our everyday view of the 
world as conscious observers 'moving' through time (which is, by the 
way, logically incoherent, in spite of being immediately clear to 
everyone); it fits naturally with tense logics.  On the other hand, 
the 4-d view arises naturally when one thinks of time as a dimension, 
and it fits naturally into untensed asssertional logic, which is why 
it is so useful in practical applications such as business and 
engineering ontologies (and AI).

Well, good luck, but you are going to have a very hard time 
explaining to either side why they should write axioms about things 
that, to them, seem to be logically impossible (a continuant to a 
perdurantist) or in gross violation of the basic rules of discourse 
and rational thought (4-d histories to an endurantist).
