(Japanese) What does this mean in english: 誰に嫌われたって良いと思ってるけど?

Question:

No google or yahoo translation answers please

Answer:

Let's rewrite:　
（たとえ）誰に 嫌われたって（＝嫌われたとしても）良い（かまわない）と思っている。

Like GonGon did, my translation would be;
"I don't care who hates me. (Whatever...)"（Or, "I wouldn't mind if someone hated me. So?"）

Japanese language prefers using "嫌う hate" with passive construction IF A PERSON
IS TALKED ABOUT
- People hate him.. やつ、みんなから嫌われてるんだよね。
- Who hates her? 彼女、誰に嫌われてるわけ？

（～しても）よい ：not mind (doing) → ～verb (past) って（も）よい（したとしても かまわない）
E.g. 自由な時間がもっと持てるなら、給料が低くなっても かまわない（= 低くなったって よい） I would be content with a lower salary if I was assured of more free time.

.... と思ってるけど is frequently used in colloquial. And you don't really have to translate it. If you do;　"in my mind", "that's what I say to myself", "So (what)?", "whatever..."

宿題やっておきなさい。Do your homework now.
後でもいいと 思ってるんだけど… I'll do it later. (How does that sound to you?)

------------- OK, here you go:

俺って けっこう 打たれ強いし, 誰に 嫌われたっていい と思ってるけど
"I'm pretty tough and I don't care what people think of me. In fact, I wouldn't care if someone hated me."

けっこう：In colloquial, "pretty" "kinda"
打たれ強い --> 逆境 gakkyou に強い thrive on adversity
≒ 他人の評価を気にしない pay no heed to to other people's criticisms/ will-wishers
