the fact that they deny Poles the right to spell their names in Polish is not that funny.
The point 14 of the Polish-Lithuanian 'Treaty on friendly relations and good neighbourly cooperation' signed in Vilnius on 26 September 1994, states clearly that members of ethnic minorities have right to use their given names and surnames in the form appropriate to the language of the ethnic minority.
Au minium, there shouldn't be any suffixes added.
Bilingual sings can/should be introduced in municipalities where more than 20 percent residents belong to a national minority (as for European Union). Similar sings are present in German,
Lemko (in Cyrillic),
... inhabited areas in Poland. When it comes to Lithuania, there are forbidden even in Šalèininkai and Vilnius districts where Poles constitute respectively 79 and 61 percent of inhabitants.
I hope they would finally appreciate what it feels like. But Lithuanians are angels in their current minority policies as compared to Poles in XVI-XVII centuries and 1920-1939. Nobody burns churches, nobody converts them into institutions of another confession, nobody burns libraries sending strzelcy groups, nobody forbids the publications.
So you want innocent people to have their rights limited and violated because of Polish-Ukrainian historical animosities and 'centuries old' grudges? Are you really such a narrow-minded person?
If I remember correctly, there was time when Orthodoxes oppressed Polish and Lithuanian Catholics/Uniates, and closed /destroyed/converted hundreds of Catholic and Uniate churches into Orthodox ones. Obviously Interbelum's Poles and Lithuanians (Orthodox churches were confiscated and destroyed also in Lithuania) strived to reverse that, and, without doubt, took revenge as well. If they reasoned like you, they would probably have slaughtered all Orthodoxes.
OUN's pamphlets were forbiden, but Szewczenko's works and Doroszenko's 'Narys istoriji Ukrajiny' published by Ukrainian Institute in Warsaw in the 30' or Orthodox, Church Slavonic bibles printed in Lviv in XVI, weren't.
c. 300,000 minority of Ukrainians (I think the numbers are higher, because in 1947 in Operation "Vistula" they forcefully deported 200,000 Ukrainians into Western Poland and it was 63 years ago, 3 generations past)
According to the census, only 27,000 Polish citizens declared themselves as ethnic Ukrainians.
don't have an opportunity to watch Ukrainian news for 26 minutes a month... Just simply having a program.
You have three Ukrainian programs in Polish public television (more than '26 minutes'/month). 'Ukraińskie wieści' is broadcasted every second Tuesday at around 6 p.m, 'Przegląd Ukraiński' - each weak, and 'Telenoviny' seems to be still aired.
Personnaly at home where I used to live, we had 2 Polish programs all day long!!!!!!!!!!, not 26 minutes a month.
That's hilarious :)
Jak odbierać ukraińskie media w Polsce
If you don't like Polish Public Television you can always take your own advice: buy a ticket and leave :) Seriously, there are far more valid accusations (in regards to treatment of ethnic minorities) against country of your origin.
It seems like somebody had good life in Lithuania under communism regime. The same was with Russians in Ukraine. They got always better possitions and access to education. They weren't eager to support Ukrainian independance, because then the competition would start on the same line. This way communism always kept tension of everyone against everyone, but not against itself.
Why don't you quote the rest of the text:
In 1950s the remaining Polish minority was a target of several attempted campaigns of Lithuanization by Communist Party of Lithuania, which tried to ban any teaching in Polish language; those attempts where however vetoed by Moscow which saw them as too nationalistic.  Polish minority, still remembering the 1950s attempts to ban Polish language,  was much more supportive of the Soviet Union and afraid that the new Lithuanian government might want to reintroduce the Lithuanization policies. 
Do you know any sources confirming that Poles were granted better positions and access to education than Lithuanians? If not, stop manipulating please.
Stop writing about history :)
