PLT CROSSES ACTIVE RWY.

Narrative

I BELIEVE THAT I TAXIED ACROSS AN ACTIVE RWY AT A TWR CTLED ARPT WITHOUT THE PROPER CLRNC TO DO SO. HOWEVER; I ALSO BELIEVE THAT THE TWR CTLR INTENDED FOR ME TO CROSS THE RWY. PREPARING FOR DEP; I CALLED GND CTL AND ASKED FOR TAXI CLRNC. HE RESPONDED WITH CLRNC TO TAXI TO RWY 35. FROM MY POS ON THE NE RAMP AT ZZZ; THIS REQUIRED XING RWY 35 AT THE N END TO GET TO THE PARALLEL TXWY ON THE W SIDE OF THE RWY. I INITIALLY HELD SHORT OF THE RWY AND ASKED THE CTLR IF I COULD CONTINUE THE TAXI. HE REPLIED IN A CONDESCENDING (SOME WOULD SAY SMART-ALECK) TONE IN THE AFFIRMATIVE; THAT THE CLRNC WAS TO TAXI TO RWY 35; IMPLYING THAT I DID NOT UNDERSTAND THE ORIGINAL CLRNC. I CROSSED THE RWY AND CONTINUED TAXIING; BUT SOON REALIZED THAT THE CTLR HAD NEVER SAID VERBATIM TO CROSS THE RWY. I SHOULD HAVE INSISTED ON THE PROPER TERMINOLOGY; BUT DID NOT. THERE WAS NO CONFLICT WITH OTHER ACFT SINCE I WAS THE ONLY AIRPLANE MOVING ON IXD AT THE TIME. MY 3 CONCERNS ARE: 1) DOES THIS CTLR FULLY UNDERSTAND THE 'TAXI TO CLRNC?' 2) SOME ATC CTLRS ARE BECOMING RUDE AND CONDESCENDING TO PLTS; WHICH CAN BE INTIMIDATING. 3) MY BIGGEST CONCERN IS THAT I ALLOWED MYSELF TO BE INTIMIDATED. I KNOW THAT YOU ARE TO HOLD SHORT OF THE ACTIVE RWY WITH THIS TYPE OF CLRNC. I HAVE STUDIED THE AIM AND WILL NOT ALLOW THIS TO HAPPEN AGAIN.
