So, you are going to take Matt Slick's words, and judge every Calvinist by them.
For your information, in Book III Chapter 21, of Calvin's "Institutes" he links "election" with "predestination".
As it was pointed out to me, "election" and "chosen" are two different Greek words.
"ἐκλεκτός,
a \{ek-lek-tos'}
1) picked out, chosen 1a) chosen by God, 1a1) to obtain salvation through Christ 1a1a) Christians are called "chosen or elect" of God 1a2) the Messiah in called "elect", as appointed by God to the most exalted office conceivable 1a3) choice, select, i.e. the best of its kind or class, excellence preeminent: applied to certain individual Christians"

Since you directly used 2 Thess. 2:13 for one of the sources, I also cite:
"αἱρέω (haireō, 138), -ῶ: [thought by some to be akin to ἄγρα, ἀγρέω, χείρ, Eng. grip, etc.; cf. Bttm. Lexil. i. 131 — but see Curtius § 117]; to take. In the Ν. Τ. in the mid. only: fut. αἱρήσομαι; 2 aor. εἱλόμην, but G L Τ Tr WH εἱλάμην, 2 Th. ii. 13, cf. [Tdf. Proleg. p. 123; WH. App. p. 165;] W. § 13, 1 a.; B. 40 (35), see ἀπέρχομαι init.; [ptcp.ἑλόμενος, Heb. xi. 25]; to take for one’s self, to choose, prefer: Phil. i. 22; 2 Th. ii. 13; μᾶλλον foll. by inf. with ἤ (common in Attic), Heb. xi. 25. [Comp.: ἀν-, ἀφ-, δι-, ἐξ-, καθ-, περι-, προ-αιρέω.]"

Now I suppose you
could make an argument with 2 Thess. 2:13, but since the two Greek words don't necessarily mean the same thing, I doubt it. If you are going to go in that direction, you drift over into the area of "Hyper-Calvinism".
The difference between the two just in scripture:
