BRABANTIO
O, thou foul thief, where hast thou stowed my
daughter? (1.2.80-81)
When Brabantio confronts Othello for eloping with Desdemona (without his permission), he accuses his new son-in-law of being a "foul thief," as if Desdemona is piece of property that has been unlawfully taken away from him. We see this same attitude earlier in the play when Iago awakens Brabantio in the middle of the night proclaiming loudly "Awake! what, ho, Brabantio! thieves! thieves! thieves! / Look to your house, your daughter and your bags! / Thieves! thieves!" (1.1.80-82). What's up with that?
History Snack: It turns out that it's pretty common in Shakespeare's plays (and sixteenth-to-seventeenth-century England in general) for daughters to be considered their father's property – unmarried women are often portrayed as something to be stolen, bartered for and/or traded by men. In The Taming of the Shrew, for example, when Baptista Minola bargains with his daughter's suitor, he treats Bianca like a possession and even refers to himself as a "merchant" who is undertaking a risky business deal (The Taming of the Shrew, 2.1.22).
BRABANTIO
Damned as thou art, thou hast enchanted her!
For I'll refer me to all things of sense,
If she in chains of magic were not bound,
Whether a maid so tender, fair, and happy,
So opposite to marriage that she shunned
The wealthy curlèd darlings of our nation,
Would ever have, to incur a general mock,
Run from her guardage to the sooty bosom
Of such a thing as thou—to fear, not to delight!
Judge me the world, if 'tis not gross in sense
That thou hast practiced on her with foul charms,
Abused her delicate youth with drugs or minerals
That weaken motion. (1.2.82-94)
Brabantio insists that Othello must have "enchanted" Desdemona – why else, asks Brabantio, would she run away from all the (white) eligible bachelors in Venice into the "sooty bosom" of the "Moor"? (Pretty obnoxious, wouldn't you say?) Brabantio's objection to his daughter's marriage to a black man gives voice to fears of miscegenation (when interracial couples marry/have sex, etc., resulting in "mixed race" children).

That thou hast practiced on her with foul charms,
Abused her delicate youth with drugs or minerals
That weaken motion. I'll have 't disputed on.
'Tis probable and palpable to thinking.
I therefore apprehend and do attach thee
For an abuser of the world, a practicer
Of arts inhibited and out of warrant.— (1.2.80-98)
Brabantio argues that Othello could not have truly won Desdemona's love – it had to be through some kind of trickery or manipulation. Brabantio couldn't be more wrong, of course.
